I just tried using XvMC hardware decoding with my geforce4 MX 440 and driver 
7174, and I got stutter (altho my mythfrontend CPU consumption dropped from 
20% to about 10%. ONce I turned that hardware decoding off, the stutter went 
away, but the CPU consumption went back up as expected. 

Not sure if this is supposed to work for my setup, but it doesn't appear to.
