Thanks for helping Hika and Mike,

OK, this is starting to do my head in :-)

I can't see why both of my frontends can access videos and tv, but only 
one of them can access the artwork and meta data.

I've just been over both of them, and as far as I can tell, the are set 
up identically.

For the users called 'tv' (which is also the same for both machines), 
~/.mythtv/config.xml is exactly the same, except for the <MediaRenderer> 
section. Both reference 192.168.0.2 with the correct password, and both 
of them are identical again to the file on the server too.

Also, I can access files on the server from both machines using nautilus.

What's going on???
