Simon, did you ever get your MP101 music client to work with mythtv's 
UPNP server?

I have recently upgraded to .21 and saw some improvement w.r.t. watching 
UPNP served up videos on a Sigma/Sayabs based client.  However, the 
Netgear MP101 music client is still acting funny.  It sill is offering 
up videos along with music.  My guess is that normal UPNP appliances 
identify them selves and rely on the server not to offer up media beyond 
the client's capabilities.  If you avoid these land mines (I think the 
client will lock up if you try to play videos) you can get to two lists. 
  A play list and an album list.  I am not sure how the play list works. 
  What is found is played then the MP101 stops.  It certainly isn't all 
the available music and there doesn't appear a way to change it.  The 
album list is severely broken.  I can only see the first album title 
which is repeated over and over again.  There must also be some sort of 
communication problem as jumping forward to see how long the album list 
might be results in a lock up.

I don't think these are Negear MP101 problems as I believe I have seen 
no such problems while running Twonkyvision.
