I strongly suggest that you go read up on Blu-ray and HD-DVD.
They have absolutely nothing to do with MediaMax. They use a content protection system called AACS that has absolutely nothing to do with MediaMax.
AACS information is competely in the public domain.
Just because they have a common denominator of digital keys is meaningless.
If anyone from SunnComm or MediaMax Technology tells you that the Blu-ray or HD-DVD formats have any connection with MediaMax or anything produced from SunnComm, you are either being lied to or you are talking to someone who is completely clueless.
