nobody interrested in this patch? imho it's really ugly to get _all_ stereo output decoded to pseudo 5.1, in most cases you only get sound from center box. Previously the only way to prevent this was to adjust to a maximum of two channels in the audio options dialog. But then you will never get 5.1 (from real 5.1 audio source) but only 2.0 downmixing. With this patch you can adjust to six channels and enable/disable the pseudo upmixing on demand with F12 or osd menu item.

much more simplified and working version (original has channels swapped without upmixer). now using FreeSurround for "no-upmixer" too with different settings.
