I cannot say more than what you can read here:
>>If I'm not mistaken, the 'mp3 surround' format is closed and there are no
>>acceptably-licensed libraries that support this format yet either.
I don't know, but i'm afraid it seems so.
One important thing for that:
There are 2 kinds of multichannel mp3's! One is the MP3 Surround and the other
is the MP3 SX (fake surround informations from regulary stereo mp3's).
Maybe the samples from http://www.all4mp3.com/music/ are MP3 SX, or differently
encoded, because these samples are played as stereo in vlc too.
But if i make MP3-Surround with BeHappy
that use the Aud-X (http://www.aud-x.com/) encoder, than vlc (0.8.5 debian) can
play this mp3 file in 5.1 surround, gstreamer gives noises and say stereo.
As you said, all surround MP3's are compatible with the existing decoders, and
can be played with these in stereo (as for the Aud-X encoder, gstreamer not
work that way).
(Sorry, but i have no more information for that atm. I will look around and
post more when i find something.)
