VideoStudio :: Photo (judder) Changing Pan And Zoom From 4:3 To 16:9?

The old photos were scanned in at 300 dpi. Many of them were then cleaned up (spots and scratches removed, etc.) using Microsoft Digital Image Pro 10 (which we also did on previous projects). My wife then began creating her project essentially using all of the VideoStudio defaults. She added a custom pan and zoom to every photo so that the slide show has some motion, and the person or object of interest in the photo gets enlarged and emphasized.

Problem 1: as some of the photos move, there is a visible twitch or judder--not sure what word I should use to describe it. It's like the picture jiggles a little as it moves. The problem is not in the burn, the DVD player or television, because you can see it happening when you watch the preview of the project in the software, edit mode. It seems to be random, I cannot discern a pattern to which photos, where on the timeline, which transition, etc., is related to the issue.

Problem 2: my wife created this project for a 4:3 aspect ratio TV, so the crop box that was used for all of the custom pan and zoom was 4:3. I would like to create a new version of the project, with all of the photos re-cropped, re-zoomed and re-panned using a 16:9 box. The problem is, I cannot figure out how to delete or un-do all of the existing 4:3 panning and zooming. I have tried opening the program with the 16:9 box checked, then opening the project file, then deleting photos from the time-line, and re-linking to a new copy of the same photo. When I open the pan and zoom box for the photo, it has a 4:3 aspect ratio crop box! Note that if I start a new project and drop the same photo on the timeline, I do get a 16:9 box for pan & zoom. So it seems that 4:3 is associated with the existing project, and I can't figure out how to get rid of it. I really don't want to have to re-create the whole thing from scratch. Is there a simple way to be able to re-do the pan & zoom at 16:9?

I tried selecting all of the photos on the timeline, right-clicking, then choosing auto pan and zoom, to see if that would re-do it using a 16:9 crop box (which could then be customized). No joy, it again used a 4:3 box.
