windvd audio renderer problem

Alrighty well i dunno whats up with this, but Windvd Really likes to reset my audio renderer to direct sound after i close it, Also Regarding that i dont think CMSS is liking windvd for some reason, because it doesnt seem to be working. iv gotten it to work once but i had to wrestel with hte render just to hear the cmss working. I usualy have it on CMSS 2 , but i normaly cant hear the dialog being outputed through all speakers unless i switch the renderer to 'auto' oO
