Some probably interesting alternatives upnp at 
https://sourceforge.net/forum/?group_id=89768 or
http://www.cybergarage.org/
if things are compiled with all dependicies one can run 'mediagate --mythtv' 
and with upnp devices like networked dvd-players or vlc with upnp compiled in 
you can access all myth recorded stuff 'everywhere'. Searching for upnp in 
this list gives you more people which are interested in these features
