What version mythtv are you running? IIRC user faginbagin identified an 
issue with how some commflag technical parameters were being calculated / 
handled and developed a series of patches to remedy. But I don't recall if 
they got pushed to fixes or not. If they did it was probably only to 
fixes/0.28, maybe.

I use the silence detection script (Australian FTA Dvb-t) 
https://www.mythtv.org/wiki/Commercial_detection_with_silences

It seems to work reasonably well on movies (maybe 75%). Not so great on TV 
series particularly channel 7.
