I've just written a FAQ for the various high definition DVD formats (currently the FAQ includes information for Blu-ray, HD DVD, EVD and FVD), going through some of the questions that have been asked in this forum, and other places recently:

It covers topics like:
* Format specifications
* Copy protection
* PS3/Xbox 360
* Comparisons
Enjoy.
