Sergey,

On IRC you mentioned a problem of improper detection of SECAM-D/K with
the Leadtek PVR2100 (XC2028 and CX23418) from an RF source.

To investigate this problem on my own, I added SECAM support to the
saa7127 driver so a PVR-350 could generate a baseband SECAM signal for
me.  The good news for me is that a PVR-350 (SAA7115 video decoder) and
HVR-1600 (CX23418 integrated video decoder) card both properly
recognized the output of the PVR-350 as SECAM.  The bad news is I could
not reproduce your problem with this setup. 

Could you please do the following and send me the output from the logs?

1. Unload the cx18 module, tuner-xc2028 module, and the other tuner
modules.

2. In /etc/modprobe.conf set the following

	options tuner-xc2028 debug=1
	options tuner debug=1

3. Then

# modprobe cx18 debug=0x33         <---- info, warn, ioctl, file
# v4l2-ctl -d /dev/video0 -i 0     <---- Tuner input
# v4l2-ctl -d /dev/video0 -s 18    <---- SECAM-D/K
# v4l2-ctl -d /dev/video0 -f <freq of good channel>
# v4l2-ctl -d /dev/video0 --log-status

And send the relevant output from dmesg and /var/log/messages,
preferably to the mailing list.  I do not need the lines that begin
"cx18-0 encoder MPEG: VIDIOC_QUERYCTRL " if that makes the output
smaller.

Thanks,
Andy
