Better do not invent something like this, otherwise we will get more and more 
logo's and overlaid commercials into the movies.

But there are some legitimations not to watch certain commercials:

-you are not the supposed customer
-you did already watch it (the most important one ;-)
-you did already buy their product

That idea can be implemented using frame-fingerprints in a library at your 
computer (i mentioned that idea before), any commercial you already watched 
and cut out by manual editing automagically get's in the library.

Later recordings are scanned _during_ recording to throw away those frames 
and safe precious disk space.

Someone with good knowledge of the MPEG2 format could extract some 
DCT-coefficients at some places in the frame directly and test if that idea 
is usable and has a sharp enough detection.

Simple cut out the same commercial from 2 different broadcasts and extract 
the values, compare them. If they have only slightly differences or are 
identical it can be done!

It would use so little cpu-cycles that it can be done (optionally) in 
realtime as well or just create the marks.vdr file if you don't trust it ;-)

The disadvantage is of course, that you have to "view" each commercial at 
least once.

The advantage is, that it would'nt drive the broadcasters crazy, IMHO.
