I am currently investigating scart switches of the types sold by
lecktropacks, etc, to see if I can effectively give my TV two RGB inputs by
using a suitable switch. I believe you can get 'auto' ones that switch in
response to the inputs.

You might want to do some Googling in uk.tech.tv.sky. There have been a
couple of threads there recently that involved choices among SCART
switching boxes. I get the impression that they are not all created
equal!

You are certainly not alone in having this problem. It seems odd to me
that manufacturers don't equip all SCART sockets with RGB, especially
now that there are so many RGB capable devices on the market. I guess it
saves them a few pennies.

Thanks for the suggestion re uk.tech.tv.sky. Yes, I'd suspect that
switchboxes vary due to the required bandwidths, impedances, crosstalks,
etc, all being reasonably demanding. So info on this will be useful.

It also seems very odd to me. I can't see that it saves them much money as
they are already employing switching, and the absence will deter those who
are aware of the problem from buying their unit! If I'd realised this was
not standard for pass through I'd have looked for an alternative. Now I
have the particular box I'll 'fix' the problem with an external switch, but
this is a measure I did not expect to be required when I bought the
receiver.

Oh well, we learn by experience, even if it sometimes costs a few quid.

Slainte,

The main snag is that all Scarts are not alike. If you stick to stereo
audio and composite video, then they act as an in/out port. But once you
go to RGB or S-Video, they become an in *or* out. So a fully wired multi
socket adaptor unit can only be used for either ins or outs. And then
there's the problem with simply paralleling video circuits - they become
double terminated.
