this is admittedly pretty far off.  but if "commflaging" could be done
very efficiently in hardware you could just delay it until playback.
it would run and if a comm. is detected seek ahead at like 200x or
however fast it can process the frames until it hits the end of the
commercial.  Then the backend doesn't have to commflag at all.
