I am trying to play a video with four channels of sound using GSVideo on my mac (10.6), and only get strange noises coming out of the speakers. If I use the default (pre 2.0) video library it works, as well as if I am playing it directly back from quicktime player.

I saw this post where a user seem to have got it to work, but that´s the only reference to multichannel sound I have found.

I don´t seem to get any error messages, but I am guessing I am using an unsupported sound codec/format? Is there a list somewhere of the sound formats which are supposed to work?

I have tested using the standard loop example, for both libraries.
