This is a pretty off-the-wall suggestion. Is there anyway to detect
V-Chip signals? I know within the US, all broadcast and cable shows
have a V-Chip signal, but it's turned off during commercials. This
would be a 100% reliable way of detecting commercials, but I have no
clue whether the signal could be picked up by myth.
I would be ironic to have something good come out of V-Chip, eh?

In my experience, blank frame detection (with strict detection) works
great most of the time in many US channels (at least the major
networks). However, outside the US, many channels don't do blank
frames. On those channels, I use logo detection and that works like a
charm. Of course, that assumes that the broadcaster turns off the
logo during commercials (which many of them do). I do have a few
channels where neither blank frames nor logo off/on is used by the
network. In those cases, I think I'm out of luck. I tried scene
change detection and it hasn't worked well, plus it wrongly flags
scenes changes inside the show or in the midst of comm breaks.
I wonder if the mythcommflag code catches things like volume levels
(many of my channels turn noticeably louder during comm breaks).
May be Chris P can give us some pointers?

I have mine set to ALL currently with manual skipping and find it
to be quite
accurate on about 90% of the channels I've recorded with about 75%
accuracy
on the last 10%. It seems to sometimes find too many or not enough
commercial
points when it gets it wrong.
I'm in the U.S.
