I figured out the issue. I had the HQ and MV quality setting set
for the mpeg4 capture and the CPU was pegged while recording.
After turning off the HQ and MV quality settings, the CPU usage
dropped to about 30% and no longer exhibited the issues while
actually looking better than it had previously. It appears that
the CPU usage may have increased slightly in the current cvs to
push it over the edge. However the bttv color adjustments make
the picture look far better.
I have no idea why the high CPU usage would result in the issues
that I saw in playback, but I'm quite happy again with my setup.
I appreciate the suggestions and help that I received and thank
you for your time.
Bob
