Here's a TIP, if your into older Movies that appear to be lacking in quality, Hook up a DVD player to a Large 68 CRT telly & watch them as they were meant to be. ANY CRT for that matter-The picture looks a lot better and aspect ratio not a problem. I watch Mcgyver and a few other Old 70' & 80's show that way-Particularly useful for those cheap $2.00 DVDs & Old Docos.
I've got a Top Notch fully fledged Home theater with all the latest tech, but nothing beats watching the old stuff of a CRT through a descent 2 channel stereo system. Just go search your local Land Fill & set up a little area for watching your old favorites, that you can't get wide screen or simply look crap on you 50" LCD.
