RGB problems with Sky + / Sony RDR-VX410 DVDR / Sony TV

I need some RGB advice please.

I have religiously followed instructions and connected

[Sky+] 'VCR Out' Scart to

[Sony RDR-VX410] DVD Recorder 'Line 3' Scart (input) , then

[Sony RDR-VX410] DVD Recorder 'AV1' Scart (output) to

[Sony TV] 'AV1 RBG' Scart (input).

RGB is enabled on all devices where appropriate.

My problem is that the 'VCR Out' on the Sky + does not output RGB, so
obviously I get sound but no picture. I can view the picture if I select
plain 'AV1 (no RGB)' on the Sony TV, with a poor picture as expected.

The Sony DVD recorder specifically says to use the 'VCR Out' scart on a Sky
box, not the main 'TV Out' Scart. So here's the rub - if I use the 'TV Out'
Scart I *do* get a picture via RGB but the colours are all smeared and
distorted, which I guess is why the Sony manual says to not use it!

There must be a way of doing this - how can I use the 'TV Out' Scart on the
Sky + box?

Thanks for *any* help.
