If I am looking at getting a panny 900 and a good screen, can you watch normal, satellite, non-hd tv on it? (P.S. I know you can WATCH it, but is the picture good?) It will be in a basement, so light is not usually a problem I was thinking of getting a 42"-50" plasma to mount on the wall, then get a roll down screen to drop in front of it for movies, the "big game", etc. I'm just wondering if it's worth buying both There is always a chance that the back half of the room (15x20' of a 15'x43' room) which has a pool table, bar, etc may be in use while people want to watch, therefore some lights on.
