This is true. I record Good Eats anytime it's on... I have over 100
episodes "mythed" =). I know that sometimes late at night they
sometimes have no commercials. Still, that doesn't mean that the same
philosophy wouldn't. Lets say the same episode ran with commercials,
then a few months later, ran commercial free. The fingerprint would
identify pre-commercial footage and post-commercial footage. If the
commercial doesn't exist, first off mythcommflag would not mark it as
a commercial anyway. Second, it could take the additional
"fingerprint" and use some logic code that says "look, if there was a
commercial break here based on the fingerprint, then how come it would
be 0 seconds long? Ignore". Or something to that effect

I don't think that'd be as big as a concern as you think. I know
exactly what you are saying, but also take in to account that audio
would/could be used in the fingerprint too. Just as in musicbrainz,
if I have a MP3 of a song that was recorded for a studio track... if I
upload the finger print, it'll match extrememly well (99% lets say) to
the studio track MP3, but it might match 60% to the accoustic version,
and 80% to the remix, etc... Either way, as long as you continue to
think of it as a way to strengthen the existing mythcommflag job, and
not as a replacement or the main factor then you should be fine.... at
least in theory =D

True, but still don't think it'll make a HUGE difference. Few
percentage points here or there. The more people that upload their
fingerprints, the smarter the overall fingerprint for the show gets.

Thanks... now only if I could code =D
