I just selected /dev/dsp from the list of available sound drivers. First I
selected the NULL driver however and noticed that the videostuttering
disappeared and the CPU was much lower.

However in my search for possible stuttering causes I also found reports on
the following:
- There was a report of stuttering when playing 60 Hzc720p HD MPEG4 via XvMC
and a Nvidia 180 driver with a modeline that was slightly below 60 Hz.
Increasing the frequency to slightly above fixed the problem.
- There was a report of stuttering which disappeared by adding an option to
xorg.conf. I do not remember exactly which option it was, but it was
something regarding syncing on events.

Also you might look at the page
http://mythtv.org/wiki/Troubleshooting:Prebuffering_pause (I have added my
problem and my solution to that page)

Best regards
Niels
