If a frontend has access to a recorded file via a normal filesystem (whether
it's a local filesystem or an nfs-mounted filesytem), the frontend should read
the file directly rather than asking the backend to stream the file.  This
feature is used by a lot of people that have their recordings directory exported
via NFS and mounted on all the remote frontends.  Some people, including myself,
have the recordings directory mounted via NFS everywhere, including the master
backend, so all backends and frontends share the same directory mounted off
a NFS server which doesn't even have Myth installed on it.  This feature helps
keep network traffic to a minimum rather than having to send the recording
data over the network twice.
