There are two pins you may need - pin 8 indicates the presence of
a signal and it's format and there is another pin to indicate whether
the source is composite or RGB data.

My TV allows me to explicitly select RGB which works even if the
pin is indicating composite so I just use that. Plus I changed the
default mode to 16:9 which means the display is always right because
Myth pillarboxes 4:3 output by default if it thinks you have a 16:9
display.

As to switching to the Myth input, well my TV is pretty much always
on that now and as the Myth box is always on when would it auto switch
to it ;-)
