I personally decided to purchase them on DVD as well as own his book and have printed out his e-books to use as guides while I practice at home. I am actually considering making you a copy of the discs so you could watch the videos without having to download them every time. I Know sitting in front of a computer can put a lot of stress on your eyes and is not nearly as comfortable as watching from the couch on the tv.
I am not as computer savy as I once was but doing something like that should not be difficult at all.
