[maxmsp] [ot] 5.1 quicktime playback on XP ?

hello list,

I'm trying to play a quicktime file with 6 audiotracks on windows xp.  
I'm quite the windows newbie and hope someone here might have a  
solution.. In osx it's no problem. I have a quicktime with videotrack  
and three stereo audio tracks. The three tracks are set to L R LS RS  
C LFE. The system audio output is set to the soundcard and in the  
audiomidi setup the 5.1 tracks are allocated to 6 outputs on my  
soundcard. In xp i'm trying the same thing. Quicktime file playback  
from quicktime player, sending the soundtracks out to 6 seperate  
outputs on a (similar, rme fface400) soundcard. Problem is that the  
xp system sound prefs seem to only want to deal with stereo output. I  
haven't been able to find any way to get more than a stereo signal  
out of the card from quicktime player. Nor can i find 5.1 system  
setup prefs anywhere. Google doesnt return any real results either ..

Any ideas ?

Thanks, Gideon.
