I connect my Tv to my Radeon 9800 via svideo. I set my display properties on theater mode. For sound I use an adapter that converts from headphone sized plug to composite in which I hook to my sony receiver. I also have a Ati Remote wonder which works from any room in the house and even outside. Its great for parties. I've been doing this for about 6 years now and find no reason to buy any additional hardware except maybe an audigy 2 card for optical sorround sound.
