Uhh, /me bad I didn't even consider a live CD :-/
I have kicked off a live CD download, and I will test it and see if its the
same.  Thanks for the tip.

I have forced the install of the F15
gstreamer-plugins-base-0.10.33-1.fc15.i686.rpm but that still exhibits the
video drop out.

Some further information, the CPU is 100% in both versions, but the frame rate
of the post 0.10.28 versions is about 2 frames per second.  
My first attempt at using oprofile seems to point at libgstdeinterlace.so, but
I am not changing gstreamer-plugins-good, only gstreamer-plugins-base!?  I
don't know if libgstvideoscale.so is having an impact on libgstvideoscale.so?

Here is the 2fps drop-out version with
gstreamer-plugins-base-0.10.33-1.fc15.i686.rpm
