[QUOTE="skistar42, post: 289277, member: 129747"] A DVD is the common disk to use for movies. It stores 4.7 GB which is fine for a standard definition movie (480i or 480p). A Blu-Ray disk is uses a laser with a shorter wavelength which allows it to store much more information (up to 50GB) which makes it ideal for a High-Definition movie (1080i or 1080p), which has a larger file size than a standard definition movie. Yes, most Blu-Ray players can play DVD's. They are "upconverted" to make them look like a Blu-Ray disk. A Blu-Ray disk needs a special Blu-Ray disk player. They cannot be played on a standard DVD Player. Like I mentioned above, a Blu-Ray disk has to be read using a laser with a smaller wavelength than a regular DVD, so a DVD player will not be able to play a Blu-Ray Disk. HD is High-Definition (720p, 1080i, 1080p). A Blu-Ray disk plays back in the highest resolution possible now (1080p). But to see the video in 1080p, you need a 1080p TV. Yes, a PS3 will be able to play a DVD as well as a Blu-Ray disk. If you have ny other questions, email me through my profile. [/QUOTE]
