I was riding my golf cart in late afternoon into the sun and saw a Ospreyfishing by finding prey and diving. I quickly set mt Canon 40D to av, iso 400 and started snapping with f6.3 to f8, I had a verh high shutter speed but none of the images were sharp. Iw as using a Canon 70-200 with a 1.4 extender for 340 total, none were sharp and of course the histogram was all to the right. My over/under compensation was .677 under and I could not get it to change. None of the exciting images were sharp. I did have IS on?

Were you shooting on ai servo? When you say you had a very high shutter speed, what do you mean? Giving us the actual number would help diagnose.
Plus, it would be great if you could post a sample image.

If you couldn't change the EC level it was probably due to the camera only turned to the first on position and not the "/" point.
Of course if shooting into the light with the camera set to underexpose a subject which is backlight in the sky or against water will result in a severely underexposed subject. In that case the subject will rarely appear to be sharp.
I am not sure how you are figuring your focal length of 340mm, a 70-200mm with a 1.4x mounted runs from 98 to 280mm.

If the background was very busy sometimes the 40D had trouble locking on the target.
