Ah ok...I did find a diagram for 23 PIN D-SUB FEMALE Amiga to SCART and a seperate one for SCART to Svideo.
In theory I should be able to bypass SCART and go RGB to S video.
If RGB analog pins 3,4,5 go to Pin 15 SCART on a RGB to SCART cable
and...
SCART pin 15 goes to S Video 4 on a SCART to S Video cable
then...
Couldn't you just go RGB 3,4,5 to S Video Pin 4?
RGB pin 10 is Composite Sync and on a SCART goes to pin 20. SCART 20 goes to pin 3 on S Video
So again couldnt RGB pin 10 go directly to S Video pin 4?
Ground to ground...
I am not an electrician or wiring expert but at 12AM my logic sounds good to me hehe
