I would have thought the same thing, except that the live TV in the EPG 
is scaled and inserted into an OSD, and that uses the same 20% cpu for 
me. So I would assume that displaying an mpeg2 preview on an OSD would 
be no different. But looking at the code, I got lost, and realized that 
it would take me a lot of studying to get up to speed. So if I was 
doing something stupid causing it not to work, or if it can't work for 
some technical reason, I'd find some simpler thing to try and tweak 
first, that had a lower learning curve.
