I've yet to look at the audio data enough to know this or not, but I've heard
and read that it's not volume, it's something else that changes that makes
it seem louder.  I don't know.  I haven't even delved into trying to process
the audio to detect commercials, that's a whole 'nother beast.  Things like
audio silence during blank-frames and such would really help proper
detection.
