I am using the circuit described on
http://www2.arnes.si/%7Emthale1/rgb.html
but I get a really awful picture. I tried vidmode=1, 2 and 3 but
I got no difference (except with vidmode=3 I get only monochrome
colors) in quality. I tried also all AV-modes of my TV (VIDEO, SCART and
S-VIDEO), but I get only a (awful) picture with VIDEO-mode. With SCART
and S-VIDEO I get only a black screen.

I thought that was possibly a problem with the 47 Ohm resistor, but I
detected, that there is no difference if there is a connection between
J2 Pin 2 and SCART Pin 16.

Then I found following hint:

But also this change changes nothing.

Has someone an idea or hint?
