I mainly use DVD Decrypt then DVD Rebuilder with CCE, and finally Burn with Nero. Every once and awhile, Nero will give me warnings when burning..... Most go like this..... "VOB file is not referenced and should not be present" "DVD video files reallocation failed" "DVD video files compliance ignored" Nero gives me the option to continue with the warnings and I do, Finally when the Burn is complete I get.... "Burn completed succesfully with warnings" This happens in maybe 1/4 of my burns. When I play the burned copy, they seem to work with out any problems. So far anyway..... I do the process the same way every time, so Why do I get warnings sometimes and other times I don't?????
I belive this problem lies with Nero not Rebuilder. Because like you said, warnings or not the dvd still plays. I haven't had one that wouldn't play
