No, I don't have a /dev/v4l/.. :-(

The frustrating thing is that it must be able to open /dev/video3
because it's finding all the names below (Composite-1, ...) when I
register the card in step 2. I found one thing I was doing wrong, but it
didn't make any difference - I'd left the video capture type as
'Standard V4L' when it should have been 'Mpeg2 encoder card'. Now my
errors look like:
# ./setup
Session management error: Authentication Rejected, reason : None of the
authentication protocols specified are supported and host-based
authentication failed
Would you like to clear all capture card
settings before starting configuration? [no] yes
Would you like to clear all program/channel
settings before starting configuration? [no]

If this is the master backend server:

with channel information.
