Hi again jmazz.

I got your pm, glad to try to help...

Is there a reason you're reluctant to post a burn log?
It will help a great deal to narrow down the issue(s)...instructions above.

Yes, AnyDVD can be a problem, but Fab should alert you that an on-the-fly-decrypter is running.
In any case, AnyDVD is a windows based driver that runs in the background. It's not sufficient just to not run it, you must disable/exit the program so it does not run. This is also true of other on-the fly decrypters, such as dvd43.
Just so were clear, don't uninstall AnyDVD, just prevent it from running while using Fab.
I generally prevent this type of application from starting in msconfig > startup. Then, if I choose to open it, I can, but it won't start every time I boot.

Like I said, there's a good chance this movie is way over compressed, but post the burn log and we'll go from there. This will answer many of the other questions.
