OK, that won't work at the moment then, but couldn't those settings be
cached? What I was suggesting in my first post was that a slave (or even
dummy) backend could be used to store settings for the local frontend. If
the local database contained file types (which could be copied from the
master backend's database periodically), it wouldn't need to connect to the

Using the local database described above. I know at the moment all frontend
settings are stored in a single database on the master backend, but there
doesn't seem to be any real reason for that - why not store local settings
in a local database? I know it would require mysql to be installed on the
frontend, that's why my original post suggested putting a backend on the

Yes it does have a way of knowing - this could be the default action if it
can't connect to the backend. At the moment, if mythfrontend can't connect
to the backend, it loads up a page asking for connection details to the
backend (IP address, user name and password details, etc), why can't it load
mythfrontend with limited functionality based on cached player settings? It
wouldn't have to use the database any more than a shell script that pings
the backend IP address and if the ping isn't returned loads xine instead of

But that's why I was wondering if it could be solved using a dummy backend
on the frontend machine. In fact, how about running two independent
networks? I have the 0.20 version installed in /usr/bin, and when the
machine is booted up, it automatically loads /usr/bin/mythfrontend. But what
is stopping me installing the SVN version (for example - or another
0.20version) complete with backend onto the downstairs PC. When the
booted up, a shell script pings the upstairs computer to determine whether
or not the backend is running, if it is running it runs
/usr/bin/mythfrontend, if it is not running it loads
/usr/local/bin/mythbackend&, then runs /usr/local/bin/mythfrontend. The
frontend stored in /usr/local, will then connect to the local backend, and
allow DVDs to be played.
