Query: Very tired of reading it

I have to work with DShow for my job. This book is the only one available (afaik)... But it is awfully written.Mark D. Pesce does not EXPLAIN anything, he just DESCRIBES a set of, more or less enhanced, SDK samples.It is a shame.I will read it from the start to the very end because I have to do so. I am really tired of this.
