I'm setting up my HTPC and I'm having some trouble configuring the GTXP to play both digital 5.1 audio for PowerDVD _AND_ for mp3s. Is this possible? I notice in the options ("other" ... the last tab) that there are three options (on the right side of the window).: Main Outputs PowerDVD Digital audio source The "mp3" selection is one of the checklist items to the left. Now, I think I can only select ONE of the options in the list of 3 to the right. It even requires a restart of Windows to work right. Can anyone help me get this configured to do both?
