I get a similar problem on certain channels but not on the majority.
For me it is stuttering audio virtually all of the time.  If I swap to
the audio description audio track video is fine again but obviously
the normal sound is not there.

As soon as I switch back to the Standard option instead of XvMC
everything goes back to normal.  I suspect it is either the fact there
are multiple audio tracks, high bitrate or some wierd audio/video
encoding that is affecting XvMC or a combination of them all.
