I have been using the PVR code recently and noticed my Slingboxes no longer play cleanly, they keep stuttering and freezing. To be sure it was not anything specific with the PVR code I cloned the official XBMC repository yesterday (Apr 28), compiled and tested with that and got the same result. A previous copy of the code from earlier in the year (Feb time?) worked without problems. Has there been changes to the video playback of WMV streams? (This is what the slingbox uses?) Has anyone else has this problem?
