In the past I've been able to make successful copies with my DVD burner, but recently i've been spitting out nothing but coasters. I've tried different movies, and I've switched media to Sony with *some* improvement, but the discs still will not play in my DVD player. When I try to play the disc it tells me "disc error" and spits it back out. (The dvd plays fine on my computer). I've also tried the same media on a different computer and it plays fine in the DVD player, so I know the problem is not with the discs or the ability of my player to read the paticular type. My DVD burner is a: Toshiba-Samsung TSSTcorp CD/DVDW TS-H552B DVD+/- RW DL I've tried updating the firmware, but gotten nowhere. The paticular model isn't supported by Samsung/Toshiba because it was manufactured for Emachines (Gateway). And I check with Emachines and they were like "firmware update?? Uhh...." What i don't understand is that I've never had a problem in the past, and i haven't changed anything with my system. Any ideas out there?
