[vdr] RGB-out problem

[Thomas Glomann <dromtom@web.de>]

Hi all,

I have built a scart plug for the J2 connector of a Rev. 1.6 board. RGB-output 
basically works but there is an annoying interference-pattern on the 
television. The cable I made does not have any shielding at all so I am not 
really surprised of the output ;)   However, I just found out that this 
pattern is somewhat connected to the audio output :
I tried to watch a NTSC DVD (got PAL-TV, so that's why I need RGB-out). The 
DVD played well (in color ;) ) but there was this pattern. Then I quit the 
DVD plugin and the tuned channels appeard. But this time, the pattern was 
gone ! I had an excellent clear, crisp, colorful picture. As a sideeffect (of 
quitting the DVD plugin probably) the sound was also gone. 

So no sound , no pattern !?

Also when I switch channels, the pattern disappears for an instant. Maybe 
because also sound is off for short period when switching. 

So should I simply disconnect the two wires at pin 6 and 8 (left and right 
audio channels)? I wouldn't need sound via scart anyway because I have a DD 
receiver (creative inspire5700).
Or can I add some kind of shielding to the cable? It is a scart connector on 
the one side and a sub-d 9pin female connector on the other side. I used an 
old serial port interface cable to connect the J2 with this scart cable. 
Seems to be a perfect solution as no soldering is need (except the scart plug 
of course)

With this solution I can no longer connect the Asus SPDIF interface card to 
the J2. Any ideas how I can easily solder the 3 wires to the existing Scart 
cable?? I am not really good at soldering and neither is my equippment. 

Thanks a lot.

Thomas
