I have 1 Nvidia 7800GT, 1 Xfi Surround Sound card. I have my surround sound and micrphone hookedup to the xfi sound card and I have this adapter with plugs hookedup to my video card. Through my video camera to the adpater plugs on my video card, I have S Video hookedup, A/V video hookedup, not the sound cable. I tried hooking the audio cable up instead of the video but the problem is that windows movie maker wants to use my micrphone to record the sound so I need to hookup my A/V out from my camera into my micrphone port or something. The video adpater is not the red, white, yellow hookup, it has one "in" and the rest are all "out" connectors
