Hi, I have a Terratec Cinergy 250 PCI card on which I plug the SCART
from my DSL TV decoder, through a SCART-Cinch adapter and then a Cinch-
A/V adapter provided with the card (A/V is a specific format).

The issue is that the signal is a black image!
My distrib is Debian testing and my kernel is a fresh 2.6.23.13.

I know the signal is good because with a Miro DC30 (Cinch input),
xawtv displays the picture.

The card is shown by lspci :
02:00.0 Multimedia controller: Philips Semiconductors SAA7133/SAA7135
Video Broadcast Decoder (rev d0)

Also the module is loaded as shown by :
dmesg | grep saa
saa7130/34: v4l2 driver version 0.2.14 loaded

I followed the indications on v4l wiki and created /etc/modprobe.d/
saa7134 with these two lines:
options saa7134 card=83 tuner=54
options tuner secam=l

But when I launch tvtime, xawtv, ou mplayer, the picture is plain
black with a little colored noise (I checked the plug is well
inserted).

Here is the result of : cat /dev/video0 | hexdump | head

Does someone have an idea? I don't know what to do next... thanks a
lot,
