Alright, i just bought a new tv tuner card, the Hauppauge WinTV-PVR 150 MCE. (http://www.hauppauge.com/Pages/products/data_pvr150mce.html) Everything is working fine, but included on the back are the Yellow White Red auxiliary line in ports, and I'm not sure how to tell the computer/card to switch to that input. I have Windows XP MCE. Thanks in advance.

Yellow is Composit video input (from such as a VCR).

White is Left channel Audio input and Red is Right channel Audio input.

colin.

that's fine, i wasn't asking that. i'm asking how to let the computer know to switch from the coaxial input to the auxiliary input. sort of like how on a tv, if you have something plugged in to the yellow red white inputs, and you go to channel 3, it switches over for you. that is what i would like to do on my computer.
