Hi, im playing Chaos Theory on my PC and i was wondering if there is any way to convert that bass guitar music that you hear on the play/view readme/uninstall menu to an mp3 format? There all SSO formats and im unsure if there is a converter for them. . .

You could try 'TotalRecorder', which will capture audio streams and save them to various formats. The newest version has the 'lame' mp3 encoder included, IIRC, or if you get an older version just locate the 'lame' encoder online and put it in the plugin directory for TotalRecorder.

EDIT:
Almost forgot, StreamRipper can do both audio and video capture.
