Hi All, OK, I received my Tosh 57hdx82 last week and am really enjoying it now that I have a handle on adjusting the picture to my liking. DVD's are simply amazing. But, like many, I'm a little disappointed in the DirecTV picture. Just not as crisp and sharp as we would like. If I invest in a HD receiver and triple LNB dish, will I get improved pictures on all channels, or just the small sampling of channels that broadcast in Hi-Def.? $600 to $800 seems like a bit much just to get better quality on 3 or 4 channels. Thanks, Gary.
