You might try issuing 'mythbackend --setverbose none,channel' (with the 
backend already running) and see what the backend log says when you try 
to tune the missing channel.  Since kaffeine works and myth doesn't it 
seems likely that some of the stream parameters aren't set in the myth db.

Afterwards, 'mythbackend --setverbose general'

I don't run dvb-s; does the mythtvsetup 'channels' section have 
something that allows you to rescan a single transponder?
