I bought a new burner a few months ago, and it worked perfectly. About 2 weeks ago it gave me my first coaster. Eversince then, pretty much every dvd I burn is trash. The burner is a Lite-On LH-18A1P. I also have a plain DVD drive installed too. When I backup a movie I put the movie in the non-burner and back it up with DVD Shrink (and AnyDVD when necessary). Then I burn at half speed which is 8x using Nero. Everything seems fine up to this point. I even verify the burn and it says it's good. But the discs will only play on the burner, but nothing else. Not the non-burner or my stand alone player. When put in the xbox 360, they will by recognized as a DVD movie but when I play them all I get is a black screen. Currently i'm using Memorex DVD+R. I don't know what's going on. It's brand new. And just 2 weeks ago, it was burning perfectly. The movies would play fine on my xbox 360. They would also play on both my non-burner and my stand alone player in the livingroom, both of which are old and extremely picky with burnt DVDs. Here is what I have ruled out. 1. Can't be the media cause I've burned a bunch of perfect dvds from the same pack. 2. Not the firmware. It's current (GL0G). I also reinstalled it. 3. It's not Nero. It's the current version. I also burned a couple with ImgBurn (which was also verified as OK after the burn) with the same effect. 4. I've changed the book type to dvd-rom on both programs. (New versions of nero apparently do it automaticly) 5. It's not because of the non-burner that I'm using to create the backups because I also tried backing up with the burner itself. 6. It's not the speed cause I alway's did half speed, and I also tried going down to 4x with no luck. 7. It's not DVD Shrink cause I've also tried backing up with DVDFab and still nothing. That's all I could think of. I'd would say that the burner is just flat out broke except that the dvds play fine when they are in the burner, but nothing else. If anyone could help me, it would be great. Thanks.
