H.264 decoding at HDTV resolutions is /very/ tough.  You probably won't
be able to do it with Myth until ffmpeg is updated to support
multi-threaded decoding of H.264 and Janne integrates the updated ffmpeg
into MythTV.  This process is in the works, so it will be done "soon"
(i.e. within a couple of years ;).  If nothing else, it should be done
before processor technology advances sufficiently that a single-core CPU
can do the decoding in realtime.
