I just got one yesterday. (Originally requested in January, then re-requested in March.) I didn't time it, but it was pretty brief. It is like a long commercial, and has a separate feature for the DVC (timeshare condos.) There was another option, can't remember what it was called, but I thought it was to jump to certain parts of the 'commercial'.
Incidentally, the kids loved watching it! I liked that it showed some of the attractions, the resort hotels, and Downtown Disney. It also came with a 20% off a purchase of $100 - I think it's good within the park shops and World of Disney shop in DTD. Sounds like $100 goes pretty fast on souvenirs, so we'll definitely use it.
