 	I would just like to add again that this procedure only works 95% 
of the time for broadcast/cable captures... about 80% of the time for tape 
transfers.  Avidemux cannot deal with chaning A/V sync throughout the 
file, and this method will have broken sync with one of these 
unfortunate captures.  The author of avidemux acknowleges this 
limitation, but says a fair bit of internal work would be needed to fix 
it.
