First the main issue is that if I burn back to back DVD's using DVDFab, the 2nd DVD will always fail the burn with no error code given. I have to shut the program down and restart it for every single burn. That hasn't always proven succesful, but it is for the most part.

2nd issue was really bad burns or crappy, jittery, skipping playback of succesful burns. The only way I fixed that was to switch to the Nero burning engine instead of the VSO engine and my burns that are successful, play wonderful now.

I've uninstalled and reinstalled and it didn't help. I had a bad stick of memory in the computer that I replaced and didn't help. At this point I'm just not sure what the issue is. I do know that with each update of DVDFab it seems to get worse. I originally was able to burn like 4 at a time before a bad one, but on the latest version, it is definitely a one shot only deal.
