Currently each "input" (which includes a firewire capture) is assumed to 
have exclusive access to the STB on which it relies.  There's not yet a 
way to make an input's use dependent upon whether or not another input 
is in use, but there have been many threads discussing exactly that 
change (and, to date, no code).

See http://www.gossamer-threads.com/lists/mythtv/dev/226134#226134 and 
the rest of that thread.  Although the thread was asking for the inverse 
(capturing multiple channels from the same input), it's the same problem.
