vob and ifo burner

I am having problems with Nero. I have 3 dvd rewrite discs. I managed to burn one movie on to them all. Now that I want to burn over them it either hangs Nero or doesn’t recognise there is a disc in there. I bought some cleaner that didn’t help. Now surely 3 dvd’s can’t all be corrupted?? I need a copier that will copy vob and ifo files can somone recomend one rather than stupid Nero??

I’m having a similar problem. I was able to get the vob files ripped off my dvd, and I cant find a burner to make a movie. If you have any luck, please e-mail me with the name of the software to burn this!! possibly a free one.
