No surround-sound with AC3

[HReaper]

Hi!

My problem is, that the intervideo-decoder has to specifically support the used soundcard - and mine isn't supported. PowerDVD correctly plays divx-movies with AC3 on my 5.1 sound-system, but it always stretches the movie to full screen-size. Is it possible to use the Cyberlink audio-decoder to create surround-sound? It seems that with bsplayer it always creates stereo sound instead of surround.

in preferences, audio tab, "for ac3 decoding, use"
have you tried to select cyberlink audio decoder (i.e. powerdvd's) ?
I think you should then be able to access its settings by right-clicking the movie window and selecting properties...
(I'm not sure but I think it should work)

I already tried this, but the settings for the cyberlink-decoder are only about two channel audio. There's no word about surround sound.
