I did the learn process with the digital cable box remote system off button on the rm-av3000, but when i turn the power off button on the rm-av3000(cable mode) it just turns the cable box off. When I first used the rm-av3000, it turned the tv off also when i turn the cable box off, which i liked, but now it just turns the cable box off so i have to push the tv button on the rm-av3000 and turn the tv off. Is there a way I can program the rm-av3000 to turn off the cable box and tv by just pushing the power off button on cable screen.
