This is a good book and offers a lot of information about Blu-Ray. I am planning to create some fancy blu-ray discs from my HD camcorder and I wanted to get familiar with the format.
I was pleasantly surprised to see that besides the technical info (codecs, limitations, etc), this book also includes some information on how to prepare your assets for blu-ray authoring.
Highly recommended! Probably the best book available to date. I subtracted a star because it could be better organized and it also could get more in depth about the compression codecs. It should be more like 4.5 stars....
