picture quality
nitfan,
I am sorry to see you having so many pq issues but I would like to say a few things that might help you out. First of all no matter how high quality your new plasma is, an SD picture will look worse the larger the screen size, there is simply no way around that. Any image contains a certain amount of information so as you spread that information over a larger area (your increased screensize) it will appear less sharp. Any upscaling of that image is an educated guess by way of sophisticated software to add information in an attempt to fill in what would be blank space on your larger screen size, but it is just a guess, the software can't make something accurate from nothing.
I too have pq and audio issues with newer DISH receivers on my 50" plasma but they are related to DISH signal quality as thy are using more compression than before resulting in lots of issues.
RGB cables will transfer an analog signal to your plasma while HDMI transfers a digital signal and should always be superior. Make sure your signal is not being scaled twice (once in the sat box and once in the plasma). Set your sat box to 1080i output and 16 X 9 format s has been suggested in previous posts, that is correct.
You only need on dish for up to 4 boxes. DISH can use 4 output LNB for four separate feeds to the various sets, so the single dish is not an issue.
Have you tried adjusting your plasma using a setup DVD such as Video Essentials or similar?
As for your claim that the SD signal was always full screen and clear on your 42" plasma, that display is also a 16 X 9 format device so you either had to have your hated gray bars or the picture was set to stretch but it didn't look as bad as the 50" unit because the picture wasn't being stretched s much. I wouldn't worry too much as all stations are going digital and most of them HD as well very soon.
Hope this helped.
