You are right, but theoretically a 99.999% solution would be enough.
There are about 200.000 frames in a movie - you would'nt even notice 
if there were a few missing at random.
Still think fingerprinting is the key, as it can be done in DC-space 
and the data are already available - how much CPU is then required for a 
recording? Maybe the expert here can provide some "real" data for it...
Of course you could still choose between just marking (failsafe) operation
and realtime-cut-out operation.

The bigger danger in all that discussion here is, that we might force the
broadcasters to directly overlay the ads on the movie in such a way (randomly)
that we can't filter it anymore someday. Some already do in other countries, 
IMHO.
