Can't this jitter effect be avoided? Isn't this the goal of the not closed
GOP-mode (but I think for DVD authoring you need closed GOP).

Wouldn't it be possible to reencode the (B/P) frames in the cut GOP as
I-Frames to avoid the jitter effect at the editpoint (for example:
IBPBBPBBPBBP IBPBBPBBPBBP IIIII IBPBBPBBPBBP IBPBBPBBPBBP).

Reencoding the whole clip isn't ideal, I guess no matter what encoding
algorithm you use there's always a loss of quality.

Daniel
