Must have players that allow the playback of either Blu-ray and HD-DVD or BOTH !!
Bluray and HD-DVD are the next generation optical discs standards that allow the playback and recording of High Definition as well as storing large amounts of data.
The products you will find here will either be one format or both and will also either have reading capabilities only or write/reading. Make you choice carefully and make sure your computer can support the playback of Hi-Definition video before making your purchase. A good tool that can help you find out whether your computer is up to the job of playing back hi-def movies can be downloaded by clicking HERE.
