Problem with dvd Fab

Can anyone help me? I’m trying to copy Pineapple Express using dvd fab It copied all the video files just fine, but when I try to burn them to dvd, it says it can’t create a directory. What does that mean and how do I fix it? Thanks for any help.

What program are you using to burn with?

I use the imgburn (Free ) and have had no problems with it.
