I signed up for 3 of the 5 required AOW dives a few weeks ago and my LDS gave me the Adventures in Diving manual and Adventures in Diving DVD as part of the package. I thought the video would have a matching video lesson for each section in the book, but it doesn't. It covers some aspects of night diving and deep diving and lightly shows you how much "fun" all the other adventure dives can be (action shots) and shows you what bunches of different equipment look like.
I consider the DVD to just be more of an incentive to read the book. I would call it a "Psych Myself Up Video" (then again, just thinking about diving gets me all psyched up). It really doesn't add much to the written material. The book is where all the useful information I wanted was and I really enjoyed tearing through each chapter.
I did my UW Nav, PPB, and Search & Recovery dives a couple weeks ago. I still have to do the Deep and Wreck dives to finish up my PADI AOW.
Good luck and don't worry about the DVD! If you REALLY want a copy of it, PM me.
