[gentoo-user] BTTV Mini-HOWTO -- how do I use multiple inputs?

["Daevid Vincent" <daevid@daevid.com>]

Followed the howto here:
http://www.faqs.org/docs/Linux-mini/BTTV.html
(which by the way is 5 years old)

I have an old hauppauge bt878 card with 4 inputs on it.

I have the video1 working fine, but how do I enable the other inputs?
They're all the same RCA kind.

I ran the MAKEDEV script, but it didn't seem to make all the video* and vbi*
nodes other than the first one...

I manually created the rest using the HOWTO as an example:
I don't know anything about nodes and all this stuff, so I guessed that the
'c' number is the same as the ones that were created, and the number next to
that increments from the one created.

If I try to take a picture:

/usr/bin/v4lctl -c /dev/video0 snap jpeg 320x240
/home/dae51d/public_html/nokia_cam.jpg
/usr/bin/v4lctl -c /dev/video1 snap jpeg 320x240
/home/dae51d/public_html/ittybitty_cam.jpg

Then the first one works fine, but the second one is failing with:

v4l2: open /dev/video1: No such device
v4l2: open /dev/video1: No such device
v4l: open /dev/video1: No such device
no grabber device available
