cpu usage skyrockets - any ideas?

Hello, I tried asking this question on mythtv-users, but got no
response. I hope I am providing enough information for someone on this
list to help me with this problem.
I have scoured the archives looking for an answer to my problem.
Somehow, I have totally screwed up my installation of mythfrontend. The
backend seems to be working just fine, but somehow, I mucked things up
and my frontend won't start correctly.
My recordings are coming in (as checked through mythweb) and I can set
things up using mythfrontend through a VNC connection.
I just upgraded my video card drivers and they seem to be happy with X
all alone. But if I start mythfrontend, the "Prescaling images" dialogs
appear, progress and disappear, but then the frontend just hangs there.
And if I check top, my cpu usage is at like 97/98% with X gobbling all
of it. I can't kill mythfrontend and the only thing that seems to work
is to kill X manually and forcefully. I can't use the mouse or keyboard
within X and I can't get to a command-line. If I have an ssh session
open to the machine though, I can do stuff no problem. So the machine is
not dying, just something about the interaction of X and mythfrontend. I
did just upgrade to .18.1 and everything was going fine.
THe only change I have made is my video card drivers. I did try to
reinstall the old ones and uninstall the new ones etc., but this made
both the NVIDIA installer and emerge (gentoo) angry and the only thing I
am now able to do successfully is install the newest driver from the
I don't really know what to look for. No errors show up in any logs
(i.e. system or mythbackend).
If I run mythfrontend -v all | tee output, I get:

Now, I don't know if it necessarily means anything that the media
monitor message is the last because I can start and use mythfrontend
(somewhat) over a VNC connection. I can start mythfrontend and the menu
comes up just fine and I can move around and even watch recordings (not
actually watch, but they show up and I can play them).
I did look into the media monitor problems some people had and tried
disabling "Monitor CD/DVD", but that did nothing.
I don't know how I screwed it up this bad. I did try reinstalling myth
and mythplugins, but that didn't work.
I really have been loving my system for over a year now and this has
been the first big problem since getting it set up initially.
Please let me know what other info you need me to let you know. I did
compile mythtv with debug support, so I can send a stack trace if need
be, but since there is not a crash or anything, I wonder if that's what
Sorry if I'm not giving you much to go on, I really want to be helpful
to all you wonderful people who have helped me in the past. Be gentle ;)
Some info on my system:
CPU: Dual P3 1000Mhz
RAM: 1GB DDR
Video Card: Nvidia GeForce 4 440 MX
Previous version of driver: 1.0-6111
Current version of driver: 1.0-7174 (and they seem to be working)
uname -a: Linux frontend1 2.6.10-gentoo-r6 #6 Sat Mar 26 17:18:25 CST
2005 i686 Pentium III (Coppermine) GenuineIntel GNU/Linux
I hope this is the type of info you need. I didn't change any config
files or anything when I upgraded drivers.
Thanks in advance,
