People are going to have problems if they use it as shown !!!

It shows CSO (Composite Sync Out) being connected to BOTH pins 19 and 20

Pin 19 = video/Sync OUT

Pin 20 = video/Sync IN

If someone is wiring this header to a SCART SOCKET they should wire it to
Pin 19 (ODD = OUT)

If someone is wiring this header to a lead teminated with a SCART PLUG they
should wire it to Pin 20 (EVEN =   IN)

All SCART leads swap pins 19 and 20 between the two ends, they also swap
1&2
(Right Audio) and 3&6 (Left Audio) as audio and Composite Video are
bidirectional so have different pins for In and Out. RGB used to same pins
for in and out so can only ever be unidirectional.

If someone DOES connect to both pins 19 and 20 then the output of the TV's
tuner will be connected to the incoming sync signal and totally screw
things
up.

One signal missing from that list is Pin 8 switching to grab the TV. If you
only use Pin16 then you would have to manually switch to the AV input on
the
TV. Some TV's may also overlay the incoming RGB signals over the nornal TV
signal if Pin 8 is not powered. Use +5V for a 16:9 image and +12V for a 4:3
image. Shouldnt be too much of a problem to find +5 and +12 inside a PC :)
