Query: Disappointed

When I purchase a book I look at all features offered with the book. E.g., if a book comes with a Learning CD I expect that cd to work with the product for which it was written. The CD that comes with this book requires QuickTime (Apple App) intead of MS Media player. This does'nt make sense.That is why I rate this pruchase with a lowly 2.
