I tried to run the glxgears thing a few minutes ago and it wouldn't 
start. It said that I needed to install mesa-utils. Computers, gotta 
love em. Anyway, got that sorted out and ran it long enough for th 
eframe rate to sort of hits it's peak. Below is the result

4141 frames in 5.0 seconds = 828.106 FPS
4710 frames in 5.0 seconds = 941.914 FPS
4730 frames in 5.0 seconds = 945.933 FPS
4703 frames in 5.0 seconds = 940.582 FPS
4651 frames in 5.0 seconds = 930.079 FPS

I'm not sure what you mean by mounting  an ISO and playing it.

What it kind of reminds me of is like when your playing a video off the 
web and it has to stop till the download catches up and then play some 
more. I can't understand why it would, but it's kind of like it's trying 
to copy the video to the hard drive and play it from there rather than 
playing off the DVD.

I've been doing a little more experimenting. First I tried my CD/DVD 
combo drive. Same effects. Then I copied a movie DVD to my hard drive [ 
one I recorded myself ]. I probably didn't play it correctly 
but............ I right clicked on some of the different files until one 
said "Play With Kafeine". The video played pretty well with just an 
occasional glitch. [ then I realized that I still had another video 
playing in Firefox on another desktop ] One thing I noticed was that 
when playing the movie from the hard drive the drive light was on less 
than when playing from the DVD.

It appears the problem is NOT Kafeine itself. I think the issue has to 
be related to why the hard drive light runs nearly continuous when 
playing a movie. Whatever is driving the hard drive is eating processor

Life is what happens while you're busy making other plans.
