Ok, a bit of reading and trial and error, I am now using the command:
"mplayer -v tv:// -tv
driver=v4l2:device=/dev/video0:normid=0:chanlist=us-cable:channel=3"
to get NTSC-M (as far as I can tell, that appears to be correct for US
cable TV).
It appears to be running properly, but I still get a black screen with
no sound.
When I selected SECAM (normid=10 through 14) I got snow. I know it is
not the correct setting, but at least it was something new coming out of
that card.
