Hi there. I'm really green when it comes to the technology stuff. Anyway, I just purchased a Sony KDL-46W4100, replacing an analog Mitsubishi projection tv. Anyway, about a month before I bought the new tv, I, not knowing then what I know now, upgraded my Dish 301 Receiver to a DIsh DVR 625 receiver. Now....I've got the new Sony hooked up to the Dish 625, and obviously the picture is not what I would expect it too be. If I upgrade to the VIP 622 HD receiver, is that going to make my picture a bit better, or what benefits would I see from doing this? I do not have any subscription HD programming from dish. Any help on how to get a better picture would be appreciated. Thanks in advance.
