The actual video content of the broadcast should not in any way be able 
to affect the correctness of the capture.  The only thing that matters 
is the video timing of the incoming signal and that's rigidly defined by 
the broadcast standard.  So I'm puzzled by how you can be seeing this.  
Can you capture 2 samples of the suspect signal and send them to me?  
Say about 5-10 seconds each, one at 720x480 and the other 640x480.
