Ahh! Help! I have had a BenQ 1620 for about 3 years now and was using it exclusively with Sony DVD-R media without ONE coaster (using Shrink and Decrypter). Sony had recently gone to "Acucore" DVD-R discs (whatever that means) and 6 or 7 out of my last 25 were garbage (dvd starts to write enough to use the disc up but then throws an error). I had some Sony DVD-RW discs for my Toshiba recorder in my home theater and they work fine, so thinking the "Accucore" discs were the problem I just tried some Fujifilm DVD-Rs and they won't work. I also tried using Deep burner thinking the software was goofy, but no dice. So, is my burner junk or what?
