See Ralph's post

for the Y/C info.

Also see Ralph's original post

for the J2 pinout.


Btw: I am having intermittent problems with both the SPDIF
audio and the Y/C video. 

The SPDIF audio works poorly right after turning on my receiver. 
The receiver's "Digital Input" goes out every few seconds for
a second, indicating that the SPDIF signal quality is insufficient.
After the receiver (!) has been running for an hour or so, the
dropout rate reduces to about one droput every 20 minutes.
I suspect that the DVB-S card outputs very poor SPDIF signal quality 
and that my receiver can handle the marginal signal only after it
hast fully warmed up. The same receiver input works fine with an
SPDIF signal from my DVD player.

The Y/C signal works fine some of the time and displays wrong
colors on my beamer at other times. Sometimes it helps to switch
to a different channel or to disconnect and reconnect the Y/C 
cable. I had a similar problem with my DVD player and I exchanged
the DVD player several times until I found one that works fine
with my beamer. I assume that the beamer is very critical about
the video timing and that (like the SPDIF signal) the Y/C signal
from the DVB card is at the margin of the spec.

So, your mileage may vary. ;-)
Good luck!
