OK - I've cracked it Here's how to get into Service Menu 2 in AV mode and adjust the overscan etc.:- You may want to select 16:9 aspect manually first as Service Menu 2 adjustments seem to be aspect-specific. - Go to analogue TV and select CH 99 - Press the DVB/Analogue button to go to DVB TV - Press TV/AV to go to AV - Enter Service Menu 1 as normal and navigate to the last item (JPEG Viewer) - Press Hold Now you can adjust the screen position and overscan etc.... I've just done this on my 42" Viera and the result with my TiVo is excellent. I can now see about an inch of blue screen to the left of the black selection bar!!
