Uncompressed AVI is overkill for something like this.
Set your project properties (File - Properties) to PAL DV (720x576,
25.000 fps) and render to this same template.
Using this as a preset allows you to do a later encode to any format you
want.
The quality loss with this template will be minimal as the encoder in
Vegas is very good.
Don't worry about Pixel; Aspect Ratio as Vegas automatically adjusts any
image to the project properties, whatever they may be.

You didn't say whether you have DVD Architect or not.
If you do, let me know how long the project is and I'll give you a
template for DVD authoring.
Also, I'd recommend downloading all of Edward Troxel's free newsletters.

Vol. 1 #8 has an article titled "Creating a Motion Slide Show with
Pan/Crop " that should interest you in adding that little bit of "oomph"
to your slide show.
