Indeed.  Although the xvmc-colour-osd patch included 8 colour pip, but just 
for fun really. :-) Unfortunately it's broken at the moment until I have time 
to catch up with Daniels second osd code reorg. 

Having said that the CLE266/CN400 should have enough spare horsepower to be 
able to decode two mpeg streams simultaneously and scale down to a pip sized 

Obviously a significant amount of work to achieve though.
