I just burned a DVD tonight, my first one, and BLAM! Right at 100%, I get an error "Burn process failed: could not perform end of disc-at-once". I've heard a few things, including the nero version (upgraded to 6.3), the media (DVD+R in this case -- DVD-R seems to have no problems??) and the drive's firmware (no updates for mine). I *do* have Roxio installed. Could this be a problem? Thanks in advance!
