seems that even the audio could not be standardized between the two camps. What
a mess!

This information was obtained from the Hexus.net site and the folks there have done a very good job,
trying to pull togehter some links to help you sort through the maze of acronyms
and technical terms. In this next phase for optical, it is imperitive that you
try to keep yourself informed. Especially if you are an early adopter to either
format, as this stuff is not cheap!
