My wife complained that the Mini is annoying because if it stays on the same channel for a while it will ask to go into sleep mode. I tried to explain that she should be watching recorded content so she doesn't have to see commercials and that the remote buttons would keep it "awake", but she has no interest in doing so. Is this set at something like 90 minutes? Has anyone found an option for it in the menus? I'd like it to at least be as long as a two-hour movie.
