I have a Mitsubishi TV connected to a Sky box and a recently purchased Liteon DVD HDD Recorder. I usually switch them all off via the remote control which leaves the red indicator lights on. When I go to switch on again next morning the channel last on the night before appears and I cannot switch to another channel unless I go to "TV Guide"/All Channels, I then get BBC 1, which is first in the Progammes list, but if I try to select another channel the picture disappears and If I leave it alone the picture will sometimes reappear quickly, other times it takes a while. If I press the Red button on the remote the letters "AV1" appear in Red, pressing the red button again gives the letters "AV1" in white but then I cannot get any picture at all. Why are the letters AV1 appearing in Red and does it make any difference, if so how do I change it to get the letters in White?
