Thanks for the reply, Howard. You've gotten me farther along than I've been.
Now I get a screen with a bottom 2/3rds blue background with a jagged top
edge. Ten or so seconds after I turn on my video source, the top third
fills with what kind of looks like large-blocky yellow lines of raster
painting (lines which angle slightly downward).
Might I ask what the commands you've provided do?
I found these instructions when I searched a few years ago, and
they've worked for me ever since. I'm certainly no expert.
In the file I saved with the instructions, I have this link,
http://blog.grantgoodyear.org/2010/09/using-mythtv-to-record-from-vcr.html
I see that it is still online and explains more than I can.
Hopefully this will help.

Okay, from that I get that my guesses were correct.
For some reason, there are two sets of utilities for controlling the
capture card (ivtv & v4l2); I'm thinking there's some overlap between
the two sets of utils; I have no idea why the separation.
I finally opened up the box; there aren't actually two cards; there's
only one (with two tuners; picture-in-picture; record two shows at once;
etc), but with two brackets; the second bracket plugs into the card,
providing the extra sets of inputs. I read on
https://www.mythtv.org/wiki/Hauppauge_PVR-500 that the coax signal is
split internally to the two tuners, so there's no need for more than one
coax input. Makes sense. (It also mentioned that the PVR-500 is
essentially just two PVR-150s on one board.)
More digging on the web provided the info that ten years ago some folks
were having trouble getting Tuner 1 to work whilst Tuner 2 worked fine.
The above-mentioned site pointed out that the /dev/video0 device is for
Tuner 1, and /dev/video1 is for Tuner 2. So I tried:
v4l2-ctl -d /dev/video1 --set-input=4 (I had moved my composite video
cable to the second RCA-video In jack)
cat /dev/video1 | mplayer -cache 8192 -
And lo and behold! I have a picture! W00t!
There's a horrible delay (about 8 seconds between movement in front of
the video camera and action on the screen), and I haven't even begun
tinkering with audio yet, and I have no idea why Tuner 2 works while
Tuner 1 does not, but I'm making progress, and I'm learning. Still, for
the year 2015?, this is too hard.
Thanks for the help! It's appreciated!
