[mythtv-users] HD live tv stuttering

[Indulis Bernsteins]

Try looking at your CPU to see if it is set to "ondemand" slowdown.  If 
your CPU is below the "speed up to take care of lots of work" threshold, 
Ubuntu will slow down the CPU to conserve power.  WIth 9.10 this threshold 
was set to 95%, so mythfrontend running VDPAU would sit at 15%, and the 
system would slow the CPU AND THE MEMORY BUS to where it could not feed 
the graphics processor!

Set to Performance profile and see if it helps!
