Hi Laur's
Relive The Magic is a company which sells a set of 20 DVD's that contain videos of just about every ride in WDW and walks around the resorts. They are fan produced so they are the FULL ride rather than the quick flashes that you get on the official DVDs but the camera work is a bit shaky. I see from the web site that they are currently doing the whole set on sale for just $39 although it says that price will go up soon.
As I said in the pre-trip report I enjoyed them so much I just had to go back and experience the rides for myself but for those who go regularly they might not be such value. Have a look at the web site and see what you think.
