No.  Timestamps are just relative values of the difference between
audio and video. eg. 0, 0.1, 0.2, etc. They have nothing to do with
real-world time.

That should not be happening at all, even with your CPU at 100%.

-mc should have no effect when capturing from a TV tuner card, only
when playing video/audio in a container like avi/mpeg.  I did not
realize that was your issue.
