Using Flipper remote with Direct TV - DirecTV

Writing for father who has a Flipper remote( simple remote to channel surf) and he gets stuck whenever the remote goes on any of the Direct TV channels - like Learn Direct TV- and I end up having to get the Direct TV remote and go to guide and get him back on a channel. I am having to do this several times a day!
The people at Flipper said they have no answers but that maybe Direct TV would have a way to hide the channels so that he doesn't end up stuck on them. ??

This question, "Using Flipper remote with Direct TV," is about DirecTV channels, programming, equipment, and sports.
