The first issue is video.  You really need an nVidia 5200 card.  The
newer cards aren't as well-supported for XvMC (they use a different
technique or API or something).  And obviously, you need to use XvMC to
get the graphics card to do most of the work.

Once you do that, you probably are fine with about a 1.5GHz cpu.  I have
an AMD 2500, and it is at something like 40% during playback.

I haven't heard any reports of one of those mini-ITX with a VIA CPU
working for HDTV, though.
