Dawgbyte, Albert posted this info about Blu-Ray:
While current optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-RAM use a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible through the use of a BD/DVD/CD compatible optical pickup and allow playback of CDs and DVDs.
It will be compatible with the current DVD's you own. Nothing sinister going on here just "progress":-)
