I just got an internal SATA DVD drive to try, instead of the external
USB drive.  This improves things slightly.

Same problem with the SATA drive.  There is drive light activity while
the buffer fills, then drive activity stops during playback, then
playback stops while the buffer refills, etc.  Feels like a lock is
preventing multithreading.  But even if this were fixed, the user
interface has poor WAF.  "Press 3, then arrow down to CD, press
select, press exit."

Same problem with the SATA drive.

This works fine now.

I didn't pursue this any further because I don't think it does lirc.

Vlc works, except for some reason it's not showing CDDB information
for album and track information like all the other players.  Maybe it
was built without cddb support?  Or contacting a different server that
doesn't know this particular CD?  "yum list vlc" gives this:
Installed Packages
vlc.i386       1.0.3-1.fc10        @rpmfusion-free-updates

So for now, I'm planning to use xine.  I'm launching it through a menu
item like this:
<text>Play Audio CD</text>
<action>EXEC xine -pwq --auto-scan=cd</action>
However, the UI with the controls (and in particular, showing the
track and elapsed time) is always appearing behind the mythfrontend
window.  If I use -pfwq, a (useless) visualization window shows up,
but not the UI window I want to see.  Any suggestions on how to change
