Shaun: My wife pointed out an extremely important factor in working with PowerPoint materials (she edits with many of our instructional media clients.) Be sure that the render setting in “Properties” (bottom of the File Menu in Vegas) is BEST, rather than the default GOOD. This can make a significant difference in the image quality of the final product.
In most renders GOOD is adequate, but with PowerPoint BEST seems to sharpen up the appearance of the text.

PS: Also be aware that in the newest version of PowerPoint, presentations can be saved as AVI files. I haven’t tried this myself but it has been reported in the Sony Editor’s Forum. This won’t help you in the current project but in future you can suggest to your clients that they save their projects this way.
