I am planning to purchase a new system and just learned about the forum. I am leaning toward the Samsung HLN 50 or 56, a denon 3803, denon 2900 dvd. Most of my viewing will be via Direct TV. ( not High Def) Would I expect the picture to be better or worse than on my current 32" Sony 15 year old tv. I have heard conflicting claims about that. Isn't there some easy muliplier to figure "minimum" distance from the screen. 2 or 3 times screen size. Thanks for the forum.
