Sorry, very new to this, I am not sure what you are asking for here.

> Have you used v4l2-ctl to ensure the tuner is set to the right tv standard (my changes default to NTSC-M)?

emunson@grover:~$ v4l2-ctl -S
Video Standard = 0x0000b000
	NTSC-M/M-JP/M-KR
emunson@grover:~$ v4l2-ctl -s ntsc
Standard set to 0000b000
emunson@grover:~$ v4l2-ctl -S
Video Standard = 0x0000b000
	NTSC-M/M-JP/M-KR

What should the default be?  NTSC-443?  When I set to NTSC-443 I see the same
behaviour as below when I try and change channels.

> Have you used v4l2-ctl or ivtv-tune to tune to the proper tv channel (the driver defaults to US channel 4)?

emunson@grover:~$ v4l2-ctl -F
Frequency: 0 (0.000000 MHz)
emunson@grover:~$ v4l2-ctl -f 259.250
Frequency set to 4148 (259.250000 MHz)
emunson@grover:~$ v4l2-ctl -F
Frequency: 0 (0.000000 MHz)


> Does v4l2-ctl --log-status still show no signal present for the '843 core in the CX23418?

Yeah,
   [94465.349721] cx18-0 843: Video signal:              not present

> Does mplayer /dev/videoN -cache 8192 have a tv station when set to the rf analog input with v4l2-ctl?

emunson@grover:~$ mplayer /dev/video0 -cache 8192
MPlayer 1.0rc4-4.4.5 (C) 2000-2010 MPlayer Team

Playing /dev/video0.
