My new remote will not toggle between HDMI1 (TV)or HDMI3 (Roku box). The menu comes up but when I toggle the up/down arrows I get a program guide in the background but the HDMI menu never moves. I can use the Roku remote to switch over to HDMI3 but to get back to TV on HDMI1 I have to use the old remote! Customer service was very nice but had no solution. I don't want to keep my old remote in use just for this purpose. I feel like there's a problem with the new remote.
