GStreamer Fails to Load Plugin

[WhatIsDot]

Hi everyone. I have a bit of a problem here. I have been having all sorts of sound problems with the latest kernel release, but I've managed to boil it down to what I think is a GStreamer problem. Info about my system:
ASRock motherboard with AMD64 Dual Core Processors (4800+) (socket 939)
Audio is on board through the USB bus.
Running Fedora 7 with kernel 2.6.22.1_41

I can hear system sounds, like login sound effects, and sound in Flash movies in Firefox, but when I try to open Totem or Rhythmbox I get the following errors:

Rhythmbox output:

It looks like the problems are related somehow, but I can't figure out what is wrong. Could it be a bug in GStreamer???

Hello:
I suspect that you are missing some gstreamer plugins ?
You can install them from the livna repo.
http://rpm.livna.org/rlowiki/

yum install gstreamer*

Interesting...
I just went and installed all the gstreamer plugins like you recommended, and I can get sound playback now, but I still have trouble getting playback from xvid, divx, and matroska and I'm still getting the same messages. I never have any of these problems if I simply boot up with the 2.6.21.1_3194 version of the kernel...
Another interesting thing, I didn't notice this, but I found this message when the kernel (2.6.22.1_41) was starting up:

...
Booting the kernel.

PCI: BIOS Bug: MCFG area at e0000000 is not E820-reserved
PCI: Not using MMCONFIG.
Red Hat nash version 6.0.9 starting
...

I'm not sure if it's related or not, but the PCI message doesn't show up when I boot up the ...3194 version of the kernel.

Thanks, Seve, for responding.

I'm even more confused now, because it says it can't find libgstffmpeg.so, but it's definitely in the directory. And if it is generating an "undefined symbol" error, then doesn't that have to mean that the error is in gstreamer itself???

EDIT:
Ok, here's some more info. At some point playback halts in rhythmbox and the program won't respond. After that, there is absolutely no audio out of any program. Also, when I try to restart the system, the progress stops at the "Shutting down smartd:" stage and I have to manually restart the computer (button). I'm starting to wonder if this is less a gstreamer problem and more a kernel audio problem...

ANOTHER EDIT:
From what I can tell, the sound is a symptom of something else. I tried booting up, logging in and just letting it sit without doing anything, and after a while I tried to start a sound and it was unresponsive. There has to be some event that occurs that causes all this stuff to happen. I have no idea how to figure it out, though.

[WhatIsDot]

Well, I guess nobody has a clue on this one. Oh well.
Right now I'm thinking that it has to do with ALSA. After "the event" takes place that causes all sound to stop and sound-related applications to lock up, I can't even get the alsamixer to run in the console. I've configured ALSA to use the usb-audio, but I think there might be a bug.
I really hope this isn't a hardware problem. If the usb-audio is using the USB Bus on the motherboard, then if there is an error on the motherboard could it effect other usb devices??? I have had a couple of instances where my USB devices have lost power mysteriously. I hope the usb-audio isn't somehow related...

Does anybody know how I can identify the problem?

...anybody...hello...?
