Avid Editing: A Guide for Beginning and Intermediate Users

I am still reading and attempting to learn Avid. I feel confident I will master and improve over time, and I know that I am more than capable (as I have learned to edit on both FCP and PremPro - the latter of which, Mr. Kauffmann, can be used on either a PC or Mac), but loved the idea of using this book in conjunction with the DVD ROM touted as existing on page XXIV in the introduction (and again referenced on pp 419-421). There was no such DVD, and mine was a new copy of the third edition text. What's more, I find it odd that references to the length of the third edition varies wildly from the description of 448pp stated in the desciption to the actual 421pp of the edition in hand. I am encouraged by the comments written by those who purchased and have used this 3rd edition text, but wonder if they were likewise shortchanged on the DVD ROM and the lack of pages?
