I received my DVD over the weekend. DVD is the only way to go, the special features and attractions are well worth it. I was pleasantly surprised at the delivery time, it took less than two weeks. The interactive map is a pretty cool feature. This DVD doesn't really contain anything different from what one can find a disneyworld.com except for some of the great photos and mini-videos.
My DVD was geared toward adults, the announcer made some comments in the very beginning of how to get the most out of WDW as adults. Plus my DVD did not contain any information on Mickey's Toontown Fair, Fantasyland, Camp Minnie & Mickey nor any other area that might have a heavy concentration of children. There was a significant section on DTD and alternative recreational activies, like golf, tennis, horseback riding, the boats, etc.
For all those that have a DVD player, Choose the DVD format.
I highly recommend it.
