The commflagger is multithreaded, and runs at one quarter resolution.  
With MPEG2, there is an optimized decode path that runs at low quality 
and high speed.  On a modern dual core processor, you should be running 
HD MPEG2 commflags at several times realtime.  A test of a 12.5Mbps 
1080i recording from CBS just ran on my 3.3GHz dual core at 310fps.
