I just bought the Sony 50inch /SXRD TV for my spouse and set it up although we are both very AV challenged. My husband does not want anything fancy like dvd player, etc.. as he pretty much only watches football and HBO, etc movies. We have TW cable and I opted for the HD box and not use the card due to all the things I've heard and he loves his guide and would be totally lost without it.. Anyway.. My question is have I set it up to get the best quality picture. I used Monster cables (red/blue/green)what are those??hooked into cable box, and the cable from the wall into the cable in and the cable out from the cable box into the TV cable in. Is this the best setup to optizmie picture quality???
