My $0.02: I was having the same unresponiveness as being described here, 
while I already was using CVS (as I read those threads before installing 
MythTV :-)

There where two issues I finally found which lead to the unresponsiveness:

1. I was running XFree without DRI acceleration. As all other modules where
   running just fine (including browsing the MP3 three in the "selection"
   screen), I never realized that.
2. After getting the radeon driver to run in XFree, the problem was more or
   less still there - afer looking at "top" output for a while I was
   noticing that XFree was regularly taking 40+% CPU when doing nothing
   impressive in MythMusic. I'm running kernel 2.6, and after some Googling
   I found out that XFree should not run nice -10 with 2.6, but nice 0.
   After re-ncing X it now run reasonably smooth.


PS: maybe something for the MythMusic developer: when tracing the 
unresponsiveness, I noticed that during cursor up/down in the play screen, 
when browsing through the music tree, that there is quite some redrawing 
which is not encessary: e.g. when browsing the second "bin", the first one 
seems also to be redrawn always.
