It's possible that a dual core Atom might be able to handle it, I doubt 
without a HD compatible video card that it would be up to the job.

Sods law HD playback on the video card under Linux seems to be either 
non-existent or in the very early stages.

Like everything though I don't doubt it'll happen eventually, not so 
sure about FLOSS Bluray playback though.

Yeah it's a shame, I presume it takes a while to develop a chipset, I 
guess Intel are probably working on addressing this.  What I'd like 
though is to get hold of one of the new low power Athlons coupled with 
the low power AMD chipset which is already available (AFAIK the CPU's 
aren't readily available yet although the motherboards are in MicroATX 
form factor).

Looks like these companies are finally starting to sit up and think 
about developing more energy efficient solutions anyway which has to be 
a good thing.

When I finally get around to building a MythTV box I'm hoping to put 
some low power and low noise components in there (but possibly not an 
Atom unless it's up to playing 720p video).
