OK, new issue for me. On my RC34 this weekend, had some issues using it to change channels and on trick play feautres. I couldn't directly change the channels by typing in numbers as some of the numbers did not work at all (0 was prominent). Also, I could not do multi-thirty second slip and some other trick play functions. On the Menu, I could not scroll up or down or select any menu options. Oddly enough, ALL of these buttons work well while using the guide. A RBR, fixed the problem. Anyone else have this issue?
