I have a Harmony One with 4 devices and several activities. I am by far not an advanced user. I've been having a problem when switching activities from dvd to TV. While using the dvd which is on HDMI 3 I switch to TV also on HDMI 3 and the tv switchs the tv to chanel 3 which is fuzzy as the cable box comes in through the HDMI input. I press the help button and the tv wil correct itself. I rechecked the remote wizard which look correct and can't understand what the remote is doing switching these activities. Any help is greatly appreciated.
