Well, I've made one myself, but soldering a vga plug is definitely not
fun.  It would be very nice if pre-made vga-scart rgb cables existed, but
I've searched for them for weeks and finally gave up.

There should be no problems with recent ATI or NVidia cards.  I use a
Radeon 9200SE because it has composite sync, but NVidia should be fine as
well.  Don't know about Matrox, S3, Intel or older cards though.

Kind regards,
