Umm I thought what I posted would make it obvious..

There is an algorithm that "watches" the stream of video.. and when you get
the split second of "active stream -> dark bit where it swaps to advert"
that's when it "thinks" there is an advert, and cuts out.. 
Hence why the MythTV boxes kept cutting out in the middle of west wing..
every time there was a power outage on the show, the mythTV thought that the
channel was swapping to adverts...
Get the idea? :-)

I wonder how it can tell the difference between an advert and the 'show' 
at all?  As far as I am aware there is no difference in the tranmitted 
signal although adverts _usually_ are louder (overall) and the colors 
are much more saturated. But automatic detection of adverts based on 
these qualities would be extremely unreliable.
