Well, resolution matches at 720x480. The frame rate's a bit off. The project runs at 29.97, while the film runs at 23.98. Hmm, I would think the resolution might have more to do with it than the frame rate, though. Sigh. I don't know.
EDIT: If it helps, I'll give a bit more detail. I converted the DVD to .avi format with HandBrake and imported the resulting files into Pinnacle. Well... that's really all the detail I have.
