What exactly do you think I need to change in the oglerc file?  I tried 
the sound driver on both OSS and ALSA, I get the same problems.

The problem with the 150mhz processor is actually due to speedstep.  
Speedstep slows down the CPU when the laptop is running on battery.  I 
have disabled speedstep in the BIOS, and now ogle is reporting 547.625 
mhz for my cpu speed.  However, I still have all the same problems when 
trying to play back the DVD.

If you want another copy of the --check output, let me know and I'll 
send it through.
