Run the frontend with -v playback and see what it is doing that causes
it.  I have seen this a couple of times when the video frame rate was
jacked up, and the audio re-encoding could not keep up.  It sounds
like your machine should cope though, so disregard my posts  :)

No need to worry about it, but it does help even on beefy machines at
times..  You can search for "judder-free playback" in the wiki.
