MythTV Vs. TiVo, Round 2 337

Egadfly writes with a comparison of the open source MythTV and the highly commercial TiVo Series 3. "How different are the two systems' available remote control devices and their graphic interfaces when it comes to ease of use? Which product should you choose if your HD signal comes OTA or if you plan to use CableCARDs? And what software features (present and future) can you expect with each product? Will loopholes in FCC regulations and cable company encryption ultimately squeeze out MythTV and other open source players?"

        CableCARD is basically a system that allows any equipment, not just provider-supplied decoders, to recieve and decrypt encrypted digital TV (typically from digital cable). It's similar to the CAMs that have been part of the DVB standard since the beginning, with the exception that CAMs were intended to be an open specification, and are supported well by Linux.

        In the U.S., at least, Cablecard is the only way for someone with cable to receive the digital channels (i.e. channels 60-1000) without using the cable company's own cable box. It's a card that fits into a slot on your DVR that allows it to decrypt the digital channels.

      My Myth setup simply uses an IR blaster to interact with the set-top box. It does precisely everything the latest HD TiVo does.

      Just a suggestion, maybe you should know what you're talking about before you dismiss Myth as "irrelevant."
      • The usage of IR blasters it not optimal. I know because I'm using it on my Series 2 TiVo with my cablebox. In general it is pretty good at changing the channels, there times when it does not change the channel correctly. Honestly, the IR blaster are making me give serious consideration to buy a Series 3 TiVo so I can use a cablecard. I think given an option, most people who use IR blasters would use an alternative method if available.

          Yah, a CableCard would be better (especially since at least Cox Cable and probably some other providers are bundling the HD STB with DVR functionality). But to say that a homebrew DVR is not functional because there is no CableCard support in Linux is just plain wrong.

            What are you talking about? Noone can tell the difference between true HD and downconverted SD? That's what he's talking about. The Tivo can record encrypted HD channels, because it has CableCard cards.

            The Tivo cannot use those channels, so it would either need to record the SD version of the channel (ESPN vs. ESPN-HD), or control the cable box & record the S-Video (standard definition) output of ESPN-HD. There are no HD encoder cards available in the home-user price range.

          Of course, not, but we both know that's a rhetorical question. OTOH, downconverted HD still looks pretty friggin' good. And there's firewire or ATSC capture options for some.

        I know you're wrong because I tried to do exactly this before I went and bought a Series 3 Tivo. The only way to have a DVR for encrypted HD is to get a Tivo or a POS cableco DVR. Your setup (unless you have some magical HD capture card that nobody makes) can only record encrypted HD content that has been downconverted to SD, and even if you did have HD capture, it would be re-encoded.

          I don't necessarily agree that downloading is ok, but just wanted to play the devil's advocate for a second.

          Take these scenarios:

          1. Let's say you have a VCR recording over the air broadcasts, and it's set to record Heroes on Monday. It does and you happily watch your show, commercials and all. Morally acceptable, right?

          2. Ok, same thing, except you fast forward through the commericials. Is this still morally acceptable? Really you're not upholding your part of the bargain (watching commercials) for the free TV you're getting.

          3. Ok, so now you discover on Tuesday that your VCR didn't change timezones properly (something about DST being moved forward or some other nonsense), and didn't record Heroes for you. You download it with commericials and watch it. Is that bad? Is there a fundamental difference between this and the first scenario?

          4. Or, say you download it with no commercials, how is that different at all than the second scenario?

          Where exactly does downloading previously broadcast material become immoral?

      While having a system that can suck down movies that are 20G a pop sounds nice in theory, it kind of falls apart once you start to really think about it. Short of having 20TB drives (or arrays) or having realtime H.264 transcoding capabilities such a system is going to be all that it's cracked up to be.

      Quality of signal is more important than resolution.

    of going on 2 years, I'd have to say it's not even close - Tivo wins for the masses. Sure, my MythTV box does what my friends' Tivos do and more. But even though they are tech guys, too, I don't see many of them going through the pain in the ass experience that is setting up and maintaining the MythTV box.

    I built my MythTV box a couple of years ago so I could record two shows at the same time (dual tuner PVR500 card) and then watch a third on our main cable. I planned on reusing olds parts as I had a fairly decent PC sitting around unused; all I needed to invest in was the tuner card and a remote. I got the MCE remote and a PVR500 for the job. All was fine and dandy until I found out that some obscure library for MythTV didn't work on my Athlon VIA motherboard chipset. A new motherboard meant new memory, and a new CPU. I also got a "HTPC" case so the thing didn't look ugly in the living room. So right off the bat my quest to do a homemade Tivo on the cheap without monthly fees set me back about $600 after throwing in a large hard drive, too. This didn't really bother me, though, as I figured it was part of doing business.

    I used Knoppmyth to set things up, and granted, it did go fairly smooth. The basic install goes along fine, it's the customization and other tweaks that take time and effort. I currently have it recording up to two shows at once, use it as a multimedia center so I can copy videos and MP3s to it and use it as a jukebox, and have used it to play emulated NES, SNES, and MAME games. But here are some things that I've noticed while using MythTV, in no particular order:

    I started off with a Ti4600 video card. It's fan started to die, so I spent money on an FX5200 card which I've read is recommended for MythTV. This went fine, and configured fine. But for some reason if I need to reset my MythTV box, the video settings revert back to a "generic" video card, and I have to recopy over the FX5200 settings from the Knoppmyth wiki. I have no idea why this is.

    Related to the above, when the generic video settings are on, recorded audio and video is out of sync. The video quality is noticeably bad, too. When it's configured correct, things are a lot better.

    I've played NES and MAME games on it. I've tried SNES, but can't get my Gravis controllers to work for some reason. Supposedly there's Genesis emulators out there, but I can't figure out how to use those within MythTV. I had issues setting up two controllers for the NES games, and they worked for awhile, but then I had some friends over and we were going to play and the 2nd controller didn't work anymore. I don't know why. Also, with the games, integrating the remote is supposed to be possible, but I don't know how to do it for my remote. It would be nice to be able to map certain keys to the remote to do emulator actions or to hit escape. Otherwise, I have to have a keyboard and mouse available when I'm using the emulators (currently via VNC). I don't have a wireless mouse/keyboard for the HTPC yet.

    After about a year, things started locking up, recordings were out of sync. Turns out MySQL defaults to logging every database action, and the database logs filled up my hard drive, killing MythTV. There was a fix in the forums, but it was a pain.

    I can only record basic cable. It can do digital, but it would have to hook up to my digital box and use IR forwarding to control the box. That would sort of defeat the purpose of being able to record a show and watch something else at the same time. Not to mention the whole reason I got it was so I could record *two* shows at the same time. I'd either need another digital box dedicated to the MythTV box, or some sort of CableCARD thing.

    Perhaps the coolest thing about MythTV is the commercial skip. After it records a show, it marks commercials, and pressing a certain button while watching them jumps to the next segment of the show. I've found this to be accurate about 50% of the time. Usually, it works for the first commercial break,

    Rigt before going to spec out a nice bunch of PC components on NewEgg and build a good box, I always pass by the Myth TV Users Mailing List [gossamer-threads.com] to make sure that I get the most relevant and updated hardware necessary, and instead end up reading a sampling of the horror stories they go through, taking a few minutes to savor the different tortures one can be subjected to (video out of sync with audio, artifacts on certain channels, MySQL database corruption, NuvExport screws up, X breaks dependencies, and all the rest) and decide to wait another few weeks, certainly the new upcoming release will be much more reliable and user-friendly? And by the way, what happened to all of the things that were done during last year's Google's 'Summer Of Code' for Myth TV ? All the great features and enhancements [mythtv.org] that were worked on?

    So I keep waiting, hoping that the next time I check the mailing list, their version of Matt Groening's Life In Hell [wikipedia.org] have died down a bit....

    Even though I am definitely doing a fair amount of Sys Admin duties on various distros, this is different, the killer part is what will happen when something screws up while I'm not around, and my wife gets mad because something didn't work, (provided I can even teach her to deal with all of these menus, options and the whole 'watching Live TV through Myth' syndrome) or my kid decides that he knows better and starts trying to hack the box himself in frustration....?

    Surely the TiVo is an attractive box for the wife and kids, but with technology changing as rapidly as it has been, it is questionable whether to invest in such a product today, unless we were hard-core TV addicts, and could justify the cost as it would immediately be recouped.

    Funnily enough, the most expedient thing I've ended up doing has been to identify the things I want to watch, and as a previous poster pointed out, just BitTorrent the shows in HD without commercials the next day, no matter where in the world I may be. (...and yes, it is sweet to download things at 10 Megs speed while in certain countries like Japan or Norway!!...LOL!)

    Net result: I hardly EVER watch any TV whatsoever, and the few shows I care about can be watched on my laptop.

    Well, I wish I had more time to tinker.... and still, major kudos to Jarod Wilson for having created this amazing open-source wonder. But as others have pointed out, for either of these two options, it's really going to all be about being able to have Myth TV interact with the CableCard slot, at least in major urban centers where cable companies rule the roost, and antenna reception is unwatchable!! The killer is that companies like Time Warner Cable are offering their own PVR deals, so they will make sure to lock anyone else out of the convenience until forced to do so by the FCC... Or that someone learns to hack the Firewire outputs of some of those new set-top decoders. Then you potentially still have HDCP to contend with. Oh, brother!! Brave new world !!

Again, that didn't work well, but a cheap Nvidia card took care of that AND gave me Svideo out so I could run a monitor and a TV as a second monitor (dual screen) at the same time. I then forced MythTV to run on the TV and got TV plus internet. It was only jerky if I did too much internet or whatever on the PC while watching TV. You do have to watch what window has focus, if you want to do some control to MythTV, but you get used to alt-tab etc.

    Because that worked so very well, at only the cost of 2 cards, I replaced the front end machine with a new 3200+ AMD socket 754 MB and chip at a little over $100. I had the case and everything else already. I also just took the 450 MHZ frontend and put it in another room, still on the MythTV network.

    The new AMD system is a dream. I run TV, internet, Openofffice.org, VNC to other machines, XP in a VMWare session, and much more. And performance is never a problem.

    MythTV is OTA, and there are plenty of stations, ABC NBC CBS PBS etc all have mutiple channels each. Fox goes HD next year, but I can record all of these SDTV using power search (record a show anytime it finds it by name, don't record dups and reruns, and skip commericals.

    nice.

    Still running on the 600 MHZ backend, but I am planning to upscale to a higher end AMD and plenty of RAM and 1.5 TB of Hard disk. This will be my main server for whatever purpose, including VMWare etc. Oh, and 4 or 5 HDTV cards, plus the SDTV cards while there is still SDTV.

    Really, this is the coolest thing for OTA TV.

    Distribution used: MythDora http://g-ding.tv/ [g-ding.tv], which is Fedora Core 5 and MythTV plus add-ons and on one install DVD. Also nice. FC6 would have been better, but this will do fine.
