Hi, I'm new here-hence i am in the newbie section. I am putting together my first HT system and I am trying to figure out what of my stuff I can use. I want to include my computer as the DVD player(it has a ATI AIW 8500DV graphics card so I can get composite out)-is this a reasonable solution? I also have a sharp 27" TV; small, I know, but I can't fit or afford much bigger so it'll have to do. Sound is my biggest problem. I have Klipsch Promedia v.2-400 speakers and a sound blaster live! value sound card. It only can do 4.1 dolby digital and THX sound. I want to get a system that can get 5.1 dolby digital. What do your recomend? starting from scratch on the sound or can I salvage somthing here?
