Thanks for all your comments - I really appreciate your help.
If you are not too burned out with this thread, perhaps you would like to see one of my horse show videos. I shot this in standard-definition with my Canon XH-A1 and edited it with PRE3. When you watch it you will not see many spectators in the stands because they are on my side of the show ring, next to the free appetizers, beer, and wine. Gotta love the horse show crowd - they really know to have a great time!
