Writing to DVD from DVD folder

I am using DVDFab 5 Gold and am having a problem with the DVD being unreadable sometimes.

When I do a Full Disc or Main Menu copy from one DVD to another…it works great. But when I try to do a Main Menu copy (or Write Data) from a DVD Folder on my hard drive, it will go through the write process but I am unable to play the DVD in any drive when it is complete. I am using the same type of media and am using the same computer and same burner.

Any suggestions on what could possibly be going on here?

Thank you
