Using MPlayer (and setting my receiver to PLII) I can clearly hear the sound as surround sound, but the "S" of "Surround" comes from the front instead of the rear speaker. This doesn't change if I reencode the audio and send it directly to the receiver. My assumption was that this simply shows the deficits of the PLII system. > Whereas in XBMC, a much lower volume is heard from > the rear speakers and the channels aren't properly > separated. Unfortunately, you can get neither support for XBMC nor MythTV here (the relevant question to them is probably: Are you reencoding my MPEG-2 two-channel audio to AC3 instead of sending it as PCM to give the receiver a better chance to know what to do?), I will hopefully open a ticket for PLII decoding, I have no idea how difficult / trivial this is given that we support encoding... > > Don't worry about MPEG-2 Multichannel, your sample > > is certainly Dolby PLII. > > Thanks.

Iirc (and I think Wikipedia also explains this), there are a few very old DVDs that use MPEG-2 Multichannel, I severely doubt that it was formalized for DVB. You can check the bitrate to be sure: I would expect that 256k are not enough for Multichannel. > Mediainfo doesn't seem to know anything about it. And as explained, Mediainfo output is rarely relevant on this mailing list.
