Is there any logic to the video input options? I've noticed on my KV28FX20 that if you connect to SCART 1 (Composite / RGB) and select 'AV1' (i.e. composite) you actually get RGB if a suitable signal is available. However, if you connect to SCART 2 (Composite / S-video) and select 'AV2' (i.e. composite) then that is exactly what you get, even if an S-video signal is available. Is this an inherent feature of SCART, or just a quirk of the TV?
