Hi Werner, >> The recording should be OK because mplayer can decode the AC3 >> stream. Live-ac3 and replaying of older recordings does work, too. > > Q: Does the recording include AC3, that means that the > setup should be configured with UseDolbyDigital = `yes'. yes the recording contains AC3: mplayer can replay the file with ac3 vdr -a 'ac3dec -P' can replay it, too I've figured out if I replay the file with vdr, the bso(replay) thread doesn't start with newer recordings AC3 replay is done then over the spdif of the dvb-card but my receiver doesn't support the strange bitformat (AC3 frames wrapped in PCM) Roland
