    I have been looking at the Sony STRDE585 & 685, and have noticed they have video inputs, what can these be used for??

    To cut down on cables to your telly, projector or plasma. You run sevaral video leads from each DVD player, sat box , VCR,etc into the amp and then one lead out to the TV. However in your case I doubt you will get better than s-video pictures. Only high-end amps (and very few anyway) can "switch" RGB or Component.

    Rather run the video leads from your DVD, etc straight to the telly's scart socket. You'll get a better picture. :)

    AV amps have video inputs and outputs which are used for switching only - ie, to keep the video signal going to a TV or projector matched to the sound going via the amp to the speakers.

    So, if you choose to use this feature, you might connect:

    DVD (Audio and Video) into the amp
    VCR (Audio and Video) In and Out of the amp
    Laserdisc (Audio and Video) into the amp
    Set Top Box (Audio and Video) into the amp
    Record deck (Audio) into the amp
    CD Player (Audio) into the amp
    Tape Deck (Audio) In and Out of the amp

    and then

    TV or Projector (Video) out of the amp into one single input.

    People who have TVs with vast numbers of Scart sockets on the back may prefer not to use this. People with TVs (or projectors) with only a single Video or SVideo input, would need to do so, if they have a large number of peripherals.

    Purists believe that using an AV amp like this degrades the video signal. Realists believe that, whilst the purist view is probably true, most equipment is of sufficiently high quality as to make any such degradation minimal.

    None of this takes account of the more esoteric signals that are produced by many DVD players - RGB and/or Component - which are intrinsically better than video or SVideo - because many amps have limited (or no) provision for switching such signals - so a direct connection for such sources is essential.

    AV amps rarely (if ever) do any sort of conversion on video signals. So, for example, if you connect a DVD into the amp using Svideo only - do not expect anything to be output from the monitor composite output on the amp.
