When you rely on the information in the video alone to seek and there
are corrupt frames (as far as I can tell) it's mostly guesswork to set
it right. Myth keeps information in the seektable as its recording to
help it know exactly where you are in the video. That's part of the
luxury of having the same software record and play back.
I don't transcode videos (except to watch on my iPhone once in a while
and it's all video from my Satellite so I rarely get broken frames) so
I don't know exactly how it works, but I suppose it would be better if
the transcoder used the seektable information when running into broken
frames. I don't know if that currently happens or if that's even
feasible since it's so specific to the project.
