Is Hollywood allergic to H.264?

Some Hollywood studios appear to be allergic to the MPEG-4 AVC (or H.264) video format. They refuse to provide their films in this format for use in high-definition DVDs. They prefer to continue utilising the good ole MPEG-2 format which is used in current DVDs. However, to have an equivalent video quality, MPEG-2 creates films twice as large as MPEG-4 and requires the use of more expensive double layer media. The sole advantage of MPEG-2 over H.264 is the ability to play it on computers with average power. High-definition DVDs are going to be used as a transitional product while waiting for the emergence of products based off of the blue laser.
