I just did a few more tests.  My last test was using Mpeg4 with a bitrate
of 6000 and an mp3 encode level 0f 5 instead of the default level of 7. 
Unfortunately, it still started stuttering and sped up.  I was hoping to
discover that a higher mp3 quality level would be able to fix it but I
guess not.  I also made another recording using rtjpeg encoding and again
it works without a problem.

The real confusing part is that the stuttering isn't always in the same
spot in the recording.  It almost seems to be a CPU issue.  But I have a
powerful enough CPU that it shouldn't be causing a problem.
