I have Windows XP home and am using Nero v126.96.36.199 bundled. Never had any problems burning DVDs until now. Every time, I get an error at the end of the burn session saying could not perform end of disc-at-once. I can burn CDs with no problem and up until now have never had problems with DVDs. After 100%, it takes a long time doing , then it fails...any suggestions???? I'm making data discs and not DVD videos.
