I don't think the codecs is the problem. I think it's more like a driver bug.

Ubuntu 9.04 and Intel graphics
by Dr. Oliver Diedrich
For Linux users who don't need absolute top-notch 3D performance, Intel is considered the preferred graphics solution, not least because the company develops its drivers as open source within the framework of the X.org project. However Intel’s drivers are currently in a state of some disarray.
Ubuntu 9.04 has arrived and includes the latest software and a whole series of interesting new features, including a much faster boot process. My enthusiasm for the new release is, none-the-less, a little muted, and all because of a single driver: the driver for Intel graphics chips. As the Ubuntu development team freely admits in its release notes, under Ubuntu 9.04 the Intel driver has "performance regressions". In plain English this means that graphics on Intel chips are slower in the new release and that on some chips the X Server may even freeze – though there is at least a workaround for the latter problem.
The problem can manifest itself through various symptoms. Ubuntu users have reported that Flash videos in full-screen mode are jerky, 3D games run unacceptably slow, the desktop is barely usable with 3D effects activated and, in extreme cases, even moving a window can be so slow that the computer becomes almost unusable. We have also observed some of these effects in tests on various Intel graphics chips.
. . . . .
I assume that the workaround mentioned herein-above will go there in this response (no, I guess not). There's another one:

Yes, Jaunty is a very nice desktop.
However for the first time, I'm getting problems with an Ubuntu distribution.
The major one is really serious, as my desktop completely freezes, and the freezes appear to be random, where only the mouse cursor can be moved. If this doesn't get fixed soon, I have to find another distro.
Other annoying bugs, are:
Burning in Brazero is slow, and incapable of burning video dvds.
Writing files to USB pen drives is slow.

I have an ATI Radeon Xpress 200M and was experiencing freezes. The custom package described in
https://bugs.launchpad.net/ubuntu/+s...49/comments/21 worked for me to fix the freezes.

I've read about these problems. As far as I know it is a problem with the Intel graphics drivers as they are overhauled at the moment. Ubuntu really should not have delivered the new drivers when they are not finished yet.

Apparently the freezes can be worked around by upgrading to a 2.6.29 or higher kernel.
In standard Ubuntu, a mainline kernel can be installed.
I run the 'realtime' kernel, and fixed things by installing the 64studio kernel, as described in the UbuntuStudio post.

I think it better to get someone's opinion before newbie me rushes right off with intentions of fixing something. Plus, I've noticed that advice given one place may seem dauntingly complicated while the same advice given some place else seems so simple that even I can (and did) implement it. I guess that, sometimes, it's just a matter of how it's written and how much is assumed that the intended audiance knows (about how to do things).
As always, I'm grateful for you all's patience and forbearance with an over ambitious moron.
