Yes, my card's inputs show up as RF, composite, and S-Video
respectively.  I have composite video coming in just fine.

As for audio, I've run a triple RCA cable (red, white, and yellow) from
the jacks on the VCR to the corresponding jacks on the bracket attached
to my Hauppauge card.  It's the same cable I used to hook the VCR to my
TV, where it worked fine.  The VCR doesn't have S-Video output.

Presumably the Hauppauge card has an audio encoder somewhere;
I just have to find it.  "ls -l /dev/ds*" shows nothing, and
"arecord -l" shows:

**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 2: ALC892 Alt Analog [ALC892 Alt Analog]
   Subdevices: 1/1
   Subdevice #0: subdevice #0
card 2: CX8801 [Conexant CX8801], device 0: CX88 Digital [CX88 Digital]
   Subdevices: 0/1
   Subdevice #0: subdevice #0

None of those appear to be part of the Hauppauge card; they're probably
on the motherboard.  Hmmm, maybe I could use one of them instead...

BTW there's no need to post copies to my e-mail; I see everything
on the list via the Usenet feed to linux.debian.user.  Thanks.

It's probably the Conexant, unless you know for sure it's on the 
motherboard. Maybe you can tell from the output of lspci with -t and -nn 
or so.

Kind regards,
Andrei

Andrei is correct.
