Ah k, have added the PCR PID.
Wouldn't the AC3 pid be the same as the audio PID though? I mean - the user
wouldn't want to play a non-AC3 audio stream AND an ac3 stream at the same
I've updated the wiki with the latest round of ideas, including the following:
zap_pids = <video_pid> <video_type> <audio_pid> <audio_type> <pcr_pid>
Would that do what you want? or does it need tweaked...
