Check out avidemux.  You can have it scan the mpeg file for black frames 
(commercials), then edit them out.  I currently do it by hand but it's 
supposed to be highly scriptable.  One suggestion...  If you edit by 
hand, start from the end and work your way forward, otherwise the frame 
numbers it determines for black will not align correctly.
