I am having difficulty burning DVD's. What happens is that I can start the burn process, everything goes fine and then at either 97 or 98 percent of the way complete the burn process quits burning. This ends up locking up my system and I end up having to hard boot the machine to release the DVD. Typically I use Nero to burn, but have tried burning an image using DVD Decrypter and have the same problem. I thought maybe a bad ASPI file so I unistalled NERO and installed the ADAPTEC ASPI driver but still had the same problem. If I burn data discs the process works fine, but if I attempt to burn Video it bugs out. I am thinking that maybe it might be the media, but it seems strange that if it were the media that it would only bug out when burning video. I am using the PIONEER A04 burner.
