The Most Compatible DVD Format: DVD-R 269

Posted by timothy from the mix-and-match-media dept.
jbridges writes "CDR-Info tested eight types of media (two examples of each media type) using five different recorders, then tested compatibility in twenty-seven standalone DVD players and twenty DVD-ROM drives. They determined that DVD-R is clearly the most compatible DVD recording format on the market. To assess the compatibility level of DVD Formats they created video content on a DVD writer using DVD-R/RW and +R/RW media. These discs were then played back in other DVD players and DVD-ROM drives -over a 1,000 combinations of drive, media and player were tested."

      I would say the biggest incompatability is the authors grasp of the english language. But seriously, I think it's time we all accept that neither format is going to die at this point and just focus on buying PLAYERS that will best play all formats... The player is the cheapest link in this chain anyway. At that point, people can decide to record on - or + based on their preference for the price/feature aspect of the media... "Do I want to pay .50 less for my disc or do I want to be able to rewrite files on the disc without erasing the whole thing?" Every situation will be different. There's no excuse for a player to come out today that doesn't fully support both formats, and THAT is where our focus should be.

        Why is there no excuse? Here is one:

        DVD+R/RW is a proprietary patented format invented by Sony corporation to push DVD FORUM's DVD-R specification out of the market. They did this by making a drive (and patenting it and licensing it) that is capable of burning both formats, but crippling the DVD-R capability to half speed of the DVD+R on the same drive (4x +, 2x -, or 8x+/4x-).

          "Why would you want to spend extra money to be compatible?"

          I would want any player I buy to be compatible with Sony and Philips as well as Panasonic for the same reason that I want any memory card reader I buy to be able to read Compact Flash and Secure Digital and Smart Media AND Memory Stick.... Because I can't control what people write things on or with, but I can control whether I can read them or not.

          Stop wasting your time trying to kill a format that will not go away and just embrace what is and make sure it won't cost you the ability to watch a DVD because you are stuck on your principles.

          Use your $$$ to buy the writer/media you prefer and let that be your vote in the format war, but refusing to push for readers that don't choke on one disc or the other is silly. They're just readers. Panasonic making their readers choke on DVD+R discs is no better than M$ making Netscape choke on content from its website. Be better than that.

    Given that DVDRW drives are $160 or less, DVDrom drives are $80 or less, DVD players (for the TV) are $100 or less, what does it really matter? All new ones are compatible with anything, so if yours happens not to work go out and buy one that can.

    The only problem with that is laptops, but slimline DVD-CDRW combo drives to retrofit to laptops are now under $200 (last time I checked, which was several months ago) and I can't immagine that a DVDRW is that much more.

    Even if your drive doesn't work and you don't want to throw it away, it's possible a firmware upgrade will let it read all -R and +R media - worked for my NEC laptop. In fact it seems that some -R[W] and +R[W] writers might be upgradable to multiformat, like the Pioneer DVR 105 (identical hardware to the 106) just as soon as the hackers finish working out what needs changing in the hex image.

          There are other advantages, such as being able to put them in a binder for higher portability. It also depends upon the size of your DVD collection. For smaller collections, the cost isn't nearly as high as you might think.

          Finally, once you start the initial backup, it's under two bucks to make a backup for each DVD you purchase. I don't think that's horribly expensive, particularly when discs go out of production all the time.

          Just a matter of preference and priorities, some people might not want to pay that extra, and that's ok.

    If you ask me, the obvious reason DVD-R got more momentum despite "DVD+R" being the theoretically better format on paper, is because right when DVD-RW drives dropped below $400 (i.e. when I purchased my Pioneer DVR-104) is because there was no such thing as DVD+R yet, just DVD+RW.

    DVD+RW media is (was?

    One important point I didn't see in the article was that many old dvd players will only play disks that have a "book type field" of DVD-ROM.
    See this link. [dvdplusrw.org]

    My old Toshiba SD2100 is that way. So it wouldn't play DVD+R disks that I made on my Memorex 4X DVD+RW burner (actually a rebranded NEC) until I reflashed the NEC firmware with HP firmware (written for HP by NEC). The HP firmware causes DVD+R disks to be written with a DVD-ROM bitsetting (for maximum compatibility). Those DVD+RW drives that default to a DVD+R bitsetting cause problems with old home DVD players. For what it's worth, I bought a DVD+RW only because that's what I have to use at work and I wanted to avoid compatibility issues.

    Any format differences in compatibility are swamped by recorder differences. That is, whether a DVD-R/RW or DVD+R/RW will work in a given player depends on both the player AND the recorder.

    They only used two -R/RW recorders, two +R/RW recorders, and one that can do all of them.

  • Give it a year or so DVD+RW will eventually take over, just look at most popular pc's coming out to market from Dell ,Hp and Gateway all the models that have DVD writers are DVD+RW. It wont be long before there will be more DVD+RW's than DVD-RW's in the market. This will make media manufactures lower media prices and DVD player manufactures make more compatible units.

  • Booktype field + why DVD+R/RW is becoming popular (Score:5, Informative)

    by GroundBounce ( 20126 ) on Sunday July 20, 2003 @04:41PM (#6486639)
    First point - All DVDs contain a field which identifies to the player the type of media. This field is called the "booktype". There are a handful of players which will refuse to play a disc if it is not tagged with one of the "acceptable" booktypes, even though the player would physically be able to play it. From the various searching around I've done, it appears that from a physical point of view, there should be very few players that can play a -R disc that can't play a +R disc (e.g., they both have very similar reflectivities, etc.).

    Most DVD writers have the ability to let you force the writing of a certain booktype field. Many of the players in the test which failed to read +R discs are likely to have done so because their firmware refused to play based on the booktype field. Setting the booktype of a +R disk to DVD-ROM or DVD-R would probably narrow the compatability gap significantly.

    An excellent technical discussion of this and other issues appears on this page [chalmers.se], near the bottom of the page.

    Second point - DVD+R/RW is becoming more popular because, outside of just compatability, there are some other subtle (or not-so-subtle, depending on your application) technical advantages. The biggest one is the ability to do fine resolution (a few bit-times) lossless linking in all recording modes.

    Again, the above page has an excellent technical discussion of this near the bottom (section labeled "What does the + in DVD+R/RW stand for").

    The bottom line is that due to the way lossless linking is performed in DVD-R in DAO mode (the most video-compatible mode), compatibility is dependent on linking data being "corrected away" by the ECC, whereas in +R/RW, the links are physically so small that a +R sector with a link is logically indistinguishable from a DVD-ROM sector.

    The primary importance of all this is that it allows real-time low-bitrate MPEG data, say from a capture card or from the internet (which will inherently cause buffer underruns due to it's low bitrate), to be directly written to DVD with compatability as high as if the data were first all written to a file and then written to DVD at once. Companies like Dell, etc., must feel that this will become a big consumer advantage because of the large amount of disk space and added inconvenience required to first store the MPEG in files and then write them to DVD.

    There are also some other subtle techincal advantages which can be seen from the above document.

    So, for consumers who want to do things like capture video from their camcorders and copy it to DVD in a simple manner, +R may be the best choice as long as their player is compatable (which it likely is since the compatibility gap isn't that big), whereas for someone who is producing DVDs which are to be distributed to many people with no knowlege of which player they have, -R may be better, although they could always increase compatability of +R by using the booktype field.

      It's also worth noting that DVD+RW discs are identical to pressed DVD-ROMs when it comes to reflectivities. The only hanging point is when drives don't comprehend the DVD+RW media identifier. Something that can be corrected on most drives by a program called DVD bitsetter (http://www.dvdplusrw.org/files/dvdbitsetter2113.z ip)

      I wondered when somebody would mention the technical advantages of DVD+R and DVD+RW. There are good reasons why Philips and partners have taken a different route.

      Mount rainier support could - when implemented correctly (grumble grumble, stupid writer programs cannot get _anything_ right) revolutionize the PC world. Finaly a large size format that you can burn easily and take to friends, modify and take back.

        I can't help but feel that your comparison of the DVD format situation is a bit backward.

        DVD-R is the VHS in the situation yes? DVD+R is the Beta right? Well which won that one? VHS won, not because it was better, it clearly wasn't, but because it was cheaper and more compatible. Beta was better, but more expensive and quite proprietary.

          Actually, VHS won the consumer war not because it was more compatible with anything (there was really nothing to be compatible with, other than Beta, which it obviously wasn't compatible with). It won the war because it was more convenient for consumers - it was more convenient because VHS could record two hours in SP mode (a length long enough to cover most movies), when at the time, Beta could not.

          DVD+R/RW has some subtle technical advantages that may turn out to give it a similar edge for consumers, like the ability to directly record variable bitrate MPEG in real time in a mode that is still highly video compatible. It's still a gamble for Phillips et al - nobody really knows whether this will end up being a big consumer advantage, but folks like Dell apparently think so, potentially enough of an advantage to overcome the slight compatibility gap. In addition, that compatibility gap is only going to get narrower (actually, better for both formats), because virtually all players being made now can play anything, and what gap exists is largely solvable with the booktype field

          Still, If I were producing DVDs for distribution to many people, and I didn't want to worry about setting booktypes, it makes sense to choose DVD-R/RW at the current time. This may change though in another few years when almost everyone has replaced their really old players and the compatibility gap has narrowed to statistical insignificance.
