Sorry, forgot to address the second portion of this...  It's very hit
and miss with actually being able to play the content.  I ended up
using AnyDVD to rip the discs in a Vista VM on my box and then close
the VM to do the testing.  Decoding TrueHD, at least in my experience,
was basically non-existent.  However I was more concerned with Video
during my testing, so really I didn't go to extremes to get it working
but the basic idea is that it doesn't work out of the box, and
definitely not with non-SVN players (specifically I mostly used
mplayer for the bulk of my testing along with Myth of course).  I
believe FFmpeg does support that, good luck actually getting it
working without studying the code.  This is all "today"; I'm very
confident we will have a much prettier picture painted by the end of
the year in all of these areas as more and more content becomes
available and more developers are able to code for the new material.

On a related topic, I've also been encoding/decoding/manipulating
AVCHD material from a Sony HD camcorder.  It also falls into the
category of needing a minimum of a 3Ghz Core2Duo and even then you are
going to be having a less-than-desirable experience for a couple of
months I'd guess.

Good luck!
