Hahaha, okay, everything worked out great. i had a rca audio cable with red and white connectors. haha so i decided try something out. i hooked up one of the white connector to the digital output of my decoder card and the white connector end to my audio digital decoder on my speakers.
then i hooked up my red connector to my s-video/rca adapter and the red connector end to my television, and everything worked out great. i got digital audio and video.
So bascially, it's now an audio/video cable.
