Yeah, that would be great if it could.  But considering people with 3GHz 
machines get huge processor usage while decoding HD mpeg4 I'd be 
surprised.  I only need to do around 500x480.  I'm going to build the 
thing anyway, because most of my content is mpeg2.  It only switches 
over to the software card when absolutely necessary.  If the M10000 
can't handle the mpeg4, then I'll just go downstairs to watch it :P, or 
lower the resolution down to something it can handle.
BTW here is a review of the M10000 from mini-ITX, that no doubt has been 
posted to this list many times already: 
It shows it just barely handling some harder stuff like dvix4 and xvid.  
But according to the reviewer the M10000 handles it just fine (not HD 
resolution, more like 720x480 resolution here).
