I buy DVDs for the video library at my US college. Am I wasting money buying DVDs now that Blu-ray has won? Our collection of VHS tapes gathers dust. Dave Null
All the high-definition players still play regular CDs and DVDs, and will for the foreseeable future. Bear in mind that most people don't actually need an HD player because they don't yet have an HD TV screen. Even if they do, many DVD players now do such a good job of "upscaling" that regular DVDs produce very acceptable results. So the changeover could be slow, and I don't think you need to worry unless Blu-ray drive manufacturers drop DVD compatibility. This is unlikely. Indeed, the Blu-ray camp is planning to offer dual-format BD/DVD discs, which should help libraries like yours make the transition.
