An anonymous reader writes "If you purchase music or movies online, what happens if the vendor goes out of business? Will you have trouble accessing your content? The question came up recently after HDGiants — provider of high-quality audio and video downloads — filed for Chapter 11 bankruptcy protection. A consumer says his content became locked inside his PC. Walmart customers suffered a similar fate last year when the retailer shut down its DRM servers (a decision they reversed after many complaints). And if Vudu dies? Your content may be locked in a proprietary box forever. Time to start buying discs again?"
