    You cannot restore what lossy compression has taken away. Any additional manipulation would just result in a guess and the end of result of that is, as you note, entirely subjective. I'm sure the vast majority of E* viewers wouldn't even know what to look for to identify poor PQ. Blocking and poor shadow detail are just two things. Colors also tend to suffer in the process.

    As bear paws pointed out, you need to be extremely careful when altering settings in any diagnostic (hidden menu) mode. But no matter what you do there, you will never be able to restore the picture to its noncompressed quality.

    Back tracking a bit more...

    That's because E* seems to compress different channels at different levels. My assumption is that this is based on available capacity vs number of channels to be offered from a particular transponder. Your eyes are not fooling you. I find that all of our locals have been highly compressed. But Discovery looks pretty good. I don't know if E10 will help alleviate this problem or if its just going to get worse so we can get more ESPN and other sports channels.

    This must be subjective for the most part. The 622 may very well have more processing power and better software, but there's only so much magic it can perform on a poor source. OTA has no requirement for compression because each transmitter has exclusive use of the bandwidth for its own signals. Obviously, your local CBS affiliate is not going to offer NBC capacity on its signal. But, I believe they could offer multiple streams and the more they do that, the less you have for a full stream HD signal.
