Ive got a pretty bad setup compared to the average htpc owner, but it works, usually. I have an creative sblive 5.1 card, and i want it to decode my 5.1 dvds, so i went into the settings in the control pannel, and set it to 5.1. easy enough i thought. Opened up windvd, and with a pair of headphones i listened to each of the jacks on the back of the card, however the only ones that were working were the black and green jack (green=mains, black i think = surrounds). So i looked in the setting of windvd(6 just for reference) and i noticed i didnt set it to ouput 5.1 from the analog soundcard, so i did that, did the headphones trick and STILL problems. im only getting audio from those two jacks, my plan is to run 2 receivers, one for the mains, one for surrounds, then split the centre/lfe jack, and run the centre to the mains (phantom center). I also have a sub with amp so i would just run the lfe jack to that. PLEASE help, im getting a projector soon(infocus x1), and need to get this thing running! If you need pc specs, its a dell l800r, 800mhz 128 megs of ram, and no, it doesnt skip every ten seconds in case youre wondering.
