I have found a temporary solution to getting a decent picture. I have chosen the YC output mode (vidmode=3) and set the TV input to YC also. The picture is much better than both composite and RGB. I hope I can work out the problems with RGB though. I don't really know how to coble all this stuf

Thanks Jon, I'm not sure I understood. Do you mean: J2 red -> resistor -> cable -> scart connector red J2 green -> resistor -> cable -> scart connector green J2 blue -> resistor -> cable -> scart connector blue And why it be bad to do it this way: J2 red -> short cable -> resistor -> scart socke

a 75Ohm resistor on the ground? Are you sure you don't mean on the composite video/luminance signal? I am electrically ignorant so it doesn't make much sense to me to put it on ground. Regards, Michal On 24/12/2003, at 12:22 AM, Emil Naepflein wrote: On Wed, 24 Dec 2003 00:18:12 +1000, Michal D

I couldn't help myself and I just tried it. It works :) Thanks. But I'm a bit concerned. Something doesn't seem quite right about the output. It's grainier than I think it should be and this is even visible in areas of black. I'm sure the SVideo output of the DXR3 didn't exhibit this. Also thin
