 	I don't recommend using avidemux to cut commercials.  It's 
incapable of dealing with varying A/V sync present occasionally in IVTV 
captures.  The result is A/V loosing sync throughout playback.  It doesn't 
happen very often with clean signals (this is why many people use it and 
write about it as "the way"), for tape transfers it definately did.  See 
my various threads on this for literally years.  Use the lossless cutting 
within Myth (or compile it standalone as mpeg2fix).  That will allow 
frame-accurate cuts, fix A/V sync timestamps, and allow for further 
processing without loosing sync.
