x11 Audio Codec?

Hey,

I'm trying to run this CD on my Mac, I've used Wine, CrossOver and WinOnX.

Every time the CD opens, it runs fine (it has audio tracks on it) I click on one of the sections to play some audio and it says "Camtaisa Player: Unable to find suitable codec to decompress the audio steam. You will not be able to hear sound"

I don't mind which program I use, but how can I fix this? I understand I need to download a codec, I tried downloading the Camtasia codec but how do I run it with the .exe file on the CD?

Thanks very much!

 

No ideas?
