Here is a review of Sandra's site. It is quite short. I actually found the zip format to be quite useful. Also, the Quicktime videos can fill the screen quite nicely thank you. They run effectively with good, loud sound and picture quality. Considering some of them were shot in the ocean, on a mountain of in places like Cuba or Egypt, the quality is good.
The best part of all is Sandra is so funny. And sweet.

As far as HD is concerned. Some sites purport to be using it, but all they are doing is remastering their content. Sandra has found it gives viewers more problems than solutions ito bytes.
