Can I hook up my HDMI Cable to my 360 without having to hook up my yellow, red and white cables? Hi, I want to hook up my 360 to my hd tv in my rec-room. The problem is my TV is mounted to the wall and I cant get behind it. The good news is that my dad recently hooked up a hdmi cable to our dvd player which is hooked up to 2 stereos. So, can anybody tell me if i can just use the HDMI Cable to play on my xbox without having the Yellow, Red and White cables.
