A friend of mine got a CSR to remove HD Access (budget issues) and he wanted to remove all the HD channels from the receiver, (without reprogramming the dish) so I took the plunge and helped. Here is a walkthrough of what I had to do and the shortcomings of the solution. The first thing I did was un-hide the SD duplicate channels. So I went to Parental, Faves, & Setup -> System Setup -> Display -> Guide HD Channels and set it to Show SD Duplicates. Once you select Show SD Duplicates the receiver will tell you that the new setting will take effect in about a minute. The message does not stay long and leaves quickly. Next, I setup a favorites list that takes the HD channels out of the guide, so I left the system menu then went to Parental, Faves, & Setup -> Favorite Channels -> Edit Settings. Finally, I went through and setup a favorites list that completely removed the HD channels. This had to be done manually because Channels I Get is not 100%. One little thing I noticed is that when you are looking at 2 channels with the same number, the HD version of that channel is always the first one displayed. In the end, I found that doing this does NOT override the receivers programming to tune to a HD channel when the channel number is entered directly into the system. The only way to ensure it does not tune to a HD channel is to select the program from the guide or use the CH +/-. Also, it did not remove the HD channels from the search results. But at least the solution kept my friend happy.
