You got improper setting there. I'll send a note and sample testing code to
you to fix the problem this afternoon after I get my urgent work here done.

Hi!

I just got myself a Sensoray Model 611 frame grabber (bt878) and I'm having
trouble making it work under Linux.

I'm running Red Hat 8.0 which already has the bttv driver (version 0.7.91)
installed as a module.
When I plugged the card, it was detected by Red Had and it added the
following line to my /etc/modules.conf :

alias char-major-81 bttv

I tryed to capture some images (using several programs) but I cant get a
clear image, all I can see is
some vertical and horizontal stripes. I live in Europe, so my cameras are
PAL. I've tryed both in PAL (768x576) and NTSC (640x480)
with the same results.

Ive been looking on the internet, reading online forums, but I can't still
make it work.
I've tryed the following /etc/modules.conf, but the image is still the same:

alias char-major-89 i2c-dev
options i2c-core i2c_debug=1
options i2c-algo-bit bit_test=1
alias char-major-81 videodev
alias char-major-81-0 bttv
options bttv card=0
options bttv pll=1

When I type:  modprobe bttv
 the following log is written to /var/log/messages:

Could you please help me getting this board to work?
