[PlanetCCRMA] XMMS Skipping on MP3 Playback

Just wondered if anyone had come across this before....?
I have XMMS with mp3 support on a CCRMA FC8 install.  When I try and 
playback MP3's via Jack into Ardour I get skipping.  Not often but 
usually enough times to make it very hard to "play" an mp3 into Ardour 
for recording over (maybe 1 time out of 8 will I get it clean).  I have 
confirmed that this something in XMMS as I can disconnect Jack & Ardour 
and it still does it.   I have also noted that when I close xmms one of 
it's libraries remains resident and I have to manually kill -9 <pid> 
otherwise Ardour gets sad and xruns on me.  All in all something is not 

I am not sure what's going on.  I do know that I had to go grab an 
external version of libmad as when I issue this:
yum install libmad
It comes back as unknown - although this was a few months back and I 
don't recall where I got libmad from now.

Just wondered if anyone else had sen this/fixed this or perhaps has 
suggestions as to what would be another Jack "aware" mp3 player I could 
try when "playing" mp3 into Ardour?

Any advice or thoughts gratefully received.

On a side note, does anyone have any suggestions on getting mp3 import 
support into Audacity without having to build from scratch.  I can 
export a wav to mp3 just fine but can't import an mp3.  It states no mp3 
support compiled in.  That makes me wonder about my libmad/lame 
environment so thought it might worth mentioning...
