Sorry, I originally misread this.  I thought you were saying "different
network" to get the myth:// URL, not the other way around.

Either way..  if BOTH machines are in an rfc 1918 zone, and the browser
is running windows, you get the myth:// URL.  If the master is set to
localhost (which prevents myth:// from working) or one of the machines
has a public internet IP, you get the streaming link.  Generally,
setting the backend's IP to localhost isn't recommended if anything else
will ever be connecting to it (in fact, it breaks things).

In the future, I'll be replacing the video_url config stuff with a
checkbox option to enable/disable the myth:// URL, use .asx files and/or
a local file:// type override for those who mount the recordings
directory via samba.
