Not sure if some royal followers are familiar with the CBC in Canada, but the CBC has a program called The Passionate Eye, and all this week they're broadcasting everything Royal. On Christmas night there will be a program on called Princess Diana: Her Life in Jewels.
Here's the link:
CBC Newsworld : Passionate Eye Showcase : Documentary
Now I know for those who don't live in Canada, might not be able to watch it, so I checked the CBC store, in case there are those who would like to purchase a copy of this series, and unfortunately, I can't find a DVD of it in the online store. SORRY
However, here's the link to the CBC online store, and there is a phone number, for those who might want to call and inquire about any of The Passionate Eye Royal Episodes.

Hope this helps....
