First post here, sorry if it has been answered before but I did a search before posting. I have a new Bravia 32 V 4000 and connected a cable box and DVD player via a Scart splitter to AV1 & a VCR to AV2. They all play OK but when I go through the menu AV2 shows up empty. When playing the VCR the TV displays AV1. If I remove the Scart in AV1 the VCR connected through AV2 doen't show up on the screen. I'm not really sure what all this means but it appears that evrthing goes through AV1. What does AV2 do?
