I've successfully watched SVT HD (Swedish HDTV test channel, 20Mbit 
H.264) on my MythTV setup, which uses an Intel Core 2 Duo E6420. Some 
tearing occurs but playback is reasonably smooth at about 90-95% CPU 
utilization.

Believe it - you're going to need at least an E6600 for completely 
smooth HDTV playback until someone either optimizes the MPEG4 codecs or 
we get GPU accelerated MPEG4 decode.
