Add the feature to study the audio waveform for 1-4 minute jumps in ambient 
Add the feature to look for the aforementioned jumps i aspect ratio
Stop commercial detection inventing ridiculously long adverts
Decouple them all from one another and allow combinations of individual 
commflag tests to individual channels
Allow for sensitivity adjustments/training on a per-channel basis
The ability to show mythcommflag a segment of the channel splash screen you 
get between ads on some channels (like on ITV) to look out for (I seem to 
recall a setting in there called logo detection, maybe this was it, but I 
never got around to playing with it)


I'm sure there's plenty more ideas other people can come up with. 
Personally, pretty much the only ads I see are on channel 4 in the UK (ITV 
and 5, er, suck) and the combo of blank frame detection in conjunction with 
scene change works quite well there.
