What exaclty causes the bad packets in the MPEG stream? Is it the PVR
firmware or ivtv? I found some code in xine's input_pvr plugin that copes
with corrupted streams: it does an close/open on the device to obtain a valid
stream again. That's probably why Freevo users didn't encounter the issue.

Do you plan to re-enable the functionality to switch inputs while a capture
is in progress in the future?
