Due to TabloTv saying my Roku premier not supporting the AC3 codec, I replaced it with a Roku Ultra this week. My Roku is attached to a 6x2 HDMI switch, which goes to the other 5 TVs in the various rooms in my home. After replacing the Roku, and programming the remotes, they lose their programming within an hour, defaulting to "insignia" TVs for all 4 remotes I use. I do not have any insignia TVs in this setup. This was not a problem with my Roku premier.
