I wanted to provide an update to my originally reported "smart card error 005" and the "No Info" problems. Dish authorized a Field Service Manager to come out yesterday to check out these problems. He did not even have to check anything saying he already knew how to correct the issues. He removed/eliminated my DP-21 switch altogether and replaced my Dish Pro LNB with a Dish PRO+ saying it was the latest and greatest. He told me they had been having problems with the DP-21 and apparently the Dish PRO+ has it's own built-in switch which is a part of the LNB.
I will need more time (switching between OTA channels and SAT) before I can definately say this has fixed the problems, but the FSR told me this was a known issue in the field and he assured me this was the fix...He didn't explain (nor did he seem to know) why all the techs I've spoken to on the phone had no clue as to this fix. I'll keep everyone up to date in a few days whether this fix is still holding.
Just a quick note to say that the above fix failed... I received the "smart card error #005" again late this afternoon after switching from a local OTA to the SAT.
