Query: Total waist of money

This book is a farce. All it does is give you an overview of DirectShow without explaining the mechanisms inside or how to approach issues that are less common. All this book does is pack whatever is written in MSDN into a nice hardcopy. There is no added value what so ever. Its fine for beginners who want to learn how to work with graph edit and do basic things with it. But why bother to buy this book if you can read everything in MSDN. I think the writer did a very systematic work of just reading Microsoft?s material in MSDN and rewriting it. Even the sample code is the same as in MSDN. I expected to learn more from a book like this then what they show you in MSDN samples. These usually are very basic, and one can expect from a book to add more value to it. There are entire topics that are not covered. I believe it?s a total waist of time and money.
