Kino doesn't work with analogue camcorders, so I've never used it.  Can you 
get a simple tv program - xawtv or tvtime or something - working?  You should 
be able to see the output of the camera in that.  If you can't, I don't think 
you will be able to stream to kino.  If you can get it working in a tv 
program, then it's a kino problem.  At least you'd know where to start 
looking.

I don't think there's much more I can help with, though, as I just don't have 
the right experience.
