Stutter during fade of volume bar and after (1 Viewer)

[mba]

Hi

In mytv when controlling the volume I get very bad stutter 5-10 secs. after the volumebar has vanished. I'm running a svn version 16660. Anybody seen this before and knows the cause? I have been looking in GUIVolumeBar.cs but I can't find anything related to a hide/transparency animation. What happens after a while when I stop changing the volume and the volume bar hides itself?

regards
Martin

Any hint would be great, or anybody experiencing the same phenomenon. Could it be related to this https://forum.team-mediaportal.com/codecs-external-players-55/stuttering-tv-purevideo-codec-24895/?
Its not just a minor stutter, as it lasts for 4-5 seconds with really bad performance. I have tried almost all conceiveable combination of codecs, the Nvidia PV is the best overall, but I just have this last annoying thing before its perfect.
