Sounds like 1.32.3 has some big changes that may break the MythTV
plugin. I've not looked but it's possible there have been some database
changes that would need changes to mythzmserver to pull the right
information from the database.  Now ZM has a stable API the plugin
should be updated to use it and remove mythzmserver since it would no
longer be used. It's unclear what the future of the plugins is since may
of them require QtWebkit,  the updated plugin would likely use it to
display live cameras and events,  has been removed in recent Qt releases
so I doubt anyone will spend much time on it so your best bet at the
moment is stick with 1.30.4.
