[mythtv-users] Commercial Flagging, what are the best

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?
