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)
