I thought I'd post some pics of my Home theater room. It is the room obove the garage so it has no windows that make it ideal for this. I run everthing through a computer with a pro sound card and HD tv tuner. The sound card has 8 outputs that I use 6. I run the sound card to some old Phase Linear and Yamaha amps that are probably 30 yrs old but still working. For video I have an Electrohome 8500lc CRT projector, the screen is 7' wide. The picture is great.
My wife did the wallpapering and I did the rest, except the carpet.
Lets see some pics of yours. And what are you using.
