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 # 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
