On exiting a stream/played file there is still a delay from sound 2-7 seconds easy.
The entire UI Freezes on exit of a stream and then you get no sound from the UI on navigation for many seconds.
WMV, not fixed, still not synced here, but it plays which is an improvement.
MP4, depends on the file and the state of Boxee. A cold boot fixes this.
That's all I have for now Marcel, gnight.
