[mythtv-users] Can't get XvMC compiled in MythTV

My dual CPU utilization is about 80-90% while displaying HD content.
Sometimes the CPUs can't keep up with certain primetime shows like
CSI. Therefore, I thought I should install XvMC. It took me days to
get my environment setup so I could compile MythTV with ./configure --
enable-xvmc. And when I finally do run the first 'make install' it
runs for about an hour and ends with something like "/etc/X11/
extensions/XvMC" can't be found. (Sorry, I didn't keep the exact
error message.)
So I set off to find the XvMC libraries and install them on my
computer. I tried:
# yum -y install libXvMC --It said there was nothing to install.
and
# yum -y install libXvMC-devel --It installed but didn't install any
libraries into the X11 directory.
Following: http://www.mythtv.org/wiki/index.php/XvMC. I tried:
# apt-get install libxvmc-dev
and
# apt-get install libxv-dev
But apt-get just complained that these packages did not exist. Does
the Wiki need to be updated? Or is it just my machine?
http://www.mythtv.org/wiki/index.php/XvMC also suggested that XvMC
was installed with the NVIDIA driver install. I so installed
1.0-9755. Of course, there still is no X11 extensions folder nor
XvMC to be found in any libraries.
I reran the compile again with ./configure --enable-xvmc and this
time, the "make install" takes just a minute. Is this typical that a
first install takes an hour and the subsequent installs take a minute?
Although the second install ran without the "X11/extensions/XvMC"
error message, my CPU utilization is still 80-90% when viewing HD
shows. Can anyone tell me:
* Where can I get the XvMC libraries?
* How do I install the XvMC libraries?
* Can I confirm the installation because the extensions directory
will be in the X11 directory? Are there specific files to look for?
* Is there any other kind of environment setup required to get XvMC
compiled into MythTV?
