"Frame data under-runs" - what are they?

[amiableakuma]

Whenever I try to author certain files now with either DVDStyler or DVDAuthorGUI - during the authoring process, I get an error with the last line reading the: "Frame data under-runs detected!"

What does this mean and how can I solve the issue?

The impression I got from reading around is that usually it's just a problem related to the specific file and that perhaps re-converting the file to MPEG might help. However, if that's not the solution, I'd rather not do that.

Someone please, let me know what you think this problem refers to and how it might be solved...

From a quick look around, it seems to be most often related to a invalid frame size, like 719 x 473 instead of 720 X 480, for example.

No, that can't be the issue - at least not in this case. All the videos I'm loading are exactly 720X480. I know somethings wierd because if I encode certain parts of the movie it will work, it just seems like there is something about the whole file that it does not like.
