The very small cable "box" is a Model HD-DTA100u/4305. The Remote is a XR2 v3-UGU. All of the buttons seem to work EXCEPT creating FAVORITE CHANNELS. I hit the Fav Button and nothing happens. What's up??? I would really like to look at fewer channels when searching for shows to watch.
As best I can tell, digital adapters (DTAs) don't have a Favorites function. You'd need replace the adapter with a full cable box. Note that your Favorites list is stored in the box, not the remote.
