I'm assuming you're using a PVR-x50. If so, see:
specifically Nick's suggestion (ProjectX).

Unfortunately no one has been able to find a "traditional" command-line
*nix application that will fix the sync to account for changing A/V sync
within the IvyTV recordings (or, at least, if they have found one, they
haven't told anyone on the IvyTV list :). From my experience, the
dirtier the signal you give the PVR, the more your sync suffers. I
typically have 1 or 2 bad frames in my 1-hour videos recorded using the
signal from my Satellite receiver--which is enough to make a noticeable
offset (as little as 1/60th second is noticeable). A recording from a
friend's MythTV box, which is connected to analog cable, had 11.278sec
of bad video (about 326 frames!) in a 2hr 5min recording, which resulted
in 5sec offset by the end of the video.
Basically, use ProjectX to demux the stream into MPEG-2 Video and an
MPEG-2 Layer 2 Audio stream, then recombine them with mplex. You can
use Project X to cut commercials when demuxing or you can demux, then
remux, then use avidemux to cut/process the video.
