I tested the frontend as I described in the above message. vmstat
shows that the CPU hits 100% every once in a while. The variation is
quite dramatic. The log shows the system running consistently around
75% busy. At one point, it drops to 27% busy. Three seconds later,
the CPU is pegged at 100%.
I believe this coincides with a fade to black followed by an action scene.
I did try overclocking my front side bus from 200 mhz to 215. Any
amount above was unstable. This did not provide enough horses to
eliminate the prebuffering pauses.
So, OK I agree that more CPU will fix my problem.
Thanks for the help.
