In the "Directory to hold recordings" you've specified in mythtv-setup 
for that backend.

If the show is available on the filesystem, it's played through the 
filesystem (whether that filesystem is local or a network filesystem).  
If it's not available on the filesystem, it's streamed by the backend 
that does have access to it via the filesystem (i.e. the backend that 
recorded it).

That's supported out of the box.  Just specify a different location for 
the recordings directory when running mythtv-setup on the different 
backends.

I'm not sure I'd say that's "preferred."  Both approaches have their 
advantages and disadvantages.
