Not exactly sure what you are trying to get it to do, could you explain it further?
When you set the favorites to "Channels I Get" it ony shows the channels you get, with a few exceptions. The most recently added channels tend to not work correctly with "Channels I Get" so a few different HBO and Cinemax channels will likely still show up even if you don't subscribe to them. Also, "Channels I Get" doesn't work all that well for the regional sports networks in the 600s. Finally, "Channels I Get" will always show the PPV and Sports channels like NFL SUnday Ticket, MLS Direct Kick, NBA League Pass, etc. because they want you to remember them and use them.
I personally always set up a favorites list though. In the same screen where you set the guide to "Channels I Get" you should also see selections for Custom 1 and 2. You can use these to make your own custom guides. The first time you select one it will have you set up the custom guide. It's sometimes easiest to start off by clicking the "Add Channels I Get" button in the lower right hand corner and then you can go back through and de-select the channels that you don't want to show up like the PPV channels, infomercial channels, shopping channels, channels that don't work correctly with "Channels I Get", etc.
Hope that helps.
