I have a BenQ DW1620A burner. I am currently burning YUDEN000-T02-00 +R discs at 4x. I rip and make the backup with DVD shrink 3.2 and burn it to DVD using DVD Decrypter. I only backup the main movie, so compression is typically not a factor. Some movies play fine…others, in my sons PS2, start jerking and then freeze about 15-20 minutes into the movie. I have tried another burner… MicroAdvantage with the same results. I have also used Memorex 4x dvd –r with the same results. I use the verify option on DVD Decrypter and have no errors. What am I doing wrong???? Any suggestions? Thanks in advance.
