If they're really being delivered to the cable box as analog signals, 
they can't be chopping out frames.  Otherwise an analog TV would fail to 
sync to them.  NTSC equipment is only designed to run at one frame rate.

Maybe there's a firmware problem with your cable box?  Or maybe they're 
providing a digital version of these channels for the cable box to decode?
