I think the same applies to v4lctl. David, Also make sure all captures on that card (/dev/video0, /dev/video24, /dev/video32) are stopped when changing TV norm, otherwise it may not take effect. BTW v4l2-ctl -d /dev/video0 --log-status will show you the driver version and the card status (the cx25843 status mostly applies to the tuner input). v4l2-ctl -d /dev/video0 -L will show you the settings of the user controls. v4l2-ctl -d /dev/video0 -S will show you what TV norm that the input is set to expect. v4l2-ctl -d /dev/video0 -I will show you the currently selected input.
