I asked to Wiley Customer Service and they send me this web:
They said that the files on the site are the only downloadable files available.
Please, for the third edition of the book ask Wiley for downloadable videos.
I hope they will listen to the writer of the book.
The book is great and it is a pity that the readers can't download all the material made by the author.
The book is very pleasant and I'm learning a lot with it.
