I would like to make a cable for some of my old console that has a female scart on one end and a vga plug on the other so i can use the passthrough on my quadscan. Can i just use the sync that is in the composite (ie pin 20 of scart ) or do i need the strip the sync from the video signal first ??? alot of these machines have rgb or composite but no s-video so would like to see which gives the best results, a doubled compsite signal or an rgb signal straight in. thanks in advance.
