I got a 32" samsung LCD not long ago and it looks great in HD on my 360, but with normal TV and DVD's the picture is very blocky around moving things. Is this just the way LCD's are or can I do something to improve it? And if I get a DVD player with a digital upscaler, will it make it any better? I haven't played a HD video on it yet so I don't know what that quality will be like. Thanks.
