During playback of live tv and/or recordings I hear short "blips", usually along with visual distortion of the video stream, either by a short freeze or lines of green and purple squares. This is not a receiving issue. This is the result of one or more updates some months ago. Unluckily too long ago to exactly track it down. However, I suppose it has to do with these syslogs:

May 29 18:00:38 [vdr] [3874] 9 cRepacker messages suppressed
May 29 18:00:38 [vdr] [3874] cAudioRepacker(0xC0): skipped 184 bytes to sync on next audio frame

I suppose the stream needs some preparation/handling before passed to xinelib.
