    As somebody trying to get to grips with surround sound/ home cinema etc, can someone please explain why some AV amps have video inputs. Does this allow automatic switching of the picture, when you change audio source, or is it some kind of reference signal? As most of the inputs seem to be S-video or composite, is it worthwhile plugging these up if you are already running RGB into your TV

    Sorry if these are stupid questions, or have been asked many times before.

    TIA

    You are correct that the video inputs allow you to switch video with the sound. This would be useful if you had a dispaly device with only one input, like some projectors or plasmas. Also most high end amps use on screen displays for setup.

    As you say there is not much point in routing the video signal though the amp if its already going as RGB via scart.

    Most people don't bother using the video routing on amps any more as they prefer to route the video signal directly to the TV.

    It is a shame that manufacturers don't release amps without video routing as not only should they be cheaper but the sound quality must be improved by not having audio and video signals together.
