I havent done anything too complicated, or with high-end computer parts or stereo eqpt. I bought a vid card that has s-video out and I got a long headphone sized cord and an adapter from the small headphonejack to rca left and right. I had a monitor hooked up to the pc durring setup, to get everything working right, insuring I could read the text (I dont have an hdtv, the text is kinda fuzzy on my tv)
I routed it through a multi-game system swithbox by Pelican. Now I press the right button, and I have video and sound on my tv and stereo. If I need to adgust anything in the computer, I typically use Remote Pc, as its easier than bringing in the monitor, or squinting.
