I just purchased a DVD+-RW DVD & CD Rewritable Drive by Micro Advantage: DVD Write Speed: 16X Rewrite: 4X CD Write: 48X. It writes single and double layer. I also got some pretty standard DVD +R's by Memorex. I've backed up DVD's with the following programs successfully: DVD Shrink & DVD XCopy Platinum. I've ALSO made a DVD format disk out of video files. I have the same problem no matter what: The DVD's work perfectly fine on a PC DVD player. However, on one home DVD player, approximately 1.5-2 years old, it gives me a "disk is dirty message" when the disk is clearly not dirty. On the other, newer DVD player (top of the line sony) I get a "disk cannot be played" message. Please note that other burned DVD's work on BOTH of these DVD Players just fine. Anyone know what's going on?
