This is actually really easy to prove. While watching a show with 
commercial skipping off, turn the volume down to where you can still hear
but you can't make out what is being said. Wait for a commercial to start.
You'll find you can understand what they're saying in the commercial just

I don't know, however, if it's enough of a difference to measure. Would
a show that has a loud section (think action movie with lots of explosions,
a lover's quarrel in a drama, etc) trigger this detection?

Perhaps a scoring system is in order? I would guess that between the 
current methods and the ideas being proposed in this thread that a scoring
system might achive the best matching. I don't know how feasable it is,
I'm just throwing out an idea for someone who actually has the knowledge
to implement to consider.
