Wow this is a sad day indeed.
http://en.wikipedia.org/wiki/HD-DVD#HD_DVD...disc_comparisonBlu-ray Discs require mandatory hard coating to prevent damaging scratches, since the disc information is closer to the surface and more vulnerable to wear and tear.
While HD DVD support for the new Dolby Digital Plus audio codec is mandatory at 3.0 Mbit/s, support in Blu-ray players is optional at 1.7 Mbit/s.
http://en.wikipedia.org/wiki/Blu-ray_Disc#Region_codesBlu-ray discs may be encoded with a region code, intended to restrict the area of the world in which they can be played; similar to the DVD region codes. Blu-ray players sold in a certain region should only be able to play discs encoded for that region. The purpose of this system is to allow motion picture studios to control the various aspects of a release (including content, date, and, in particular, price) according to the region. Discs may also be produced without region coding, so they can be played on all devices.
Also anyone remember rootkit sony music cds?
"There is much speculation to what extent the actions taken by this software are a violation of various laws against unauthorized tampering with computers, or laws regarding invasion of privacy by "spyware", and how they subject Sony and First 4 Internet to legal liability. The States of California, New York, and Texas, as well as Italy, have already taken legal action against both companies and more class action lawsuits are likely."

"Princeton researcher Alex Halderman discovered[17] that on nearly every XCP CD, code which uses a modified version from Jon Johansen's DRMS software which allows to open Apple Computer's FairPlay DRM is included. He found the code to be inactive, but fully functional as he could use it to insert songs into Fairplay. DRMS, mpg123 and VLC are licensed under the GNU General Public License (GPL). The other software found, like LAME is licensed under the Lesser General Public License (LGPL), also as free software. If the claims are correct, then Sony/BMG was distributing copyrighted material illegally."

"On a National Public Radio program, Thomas Hesse, President of Sony BMG's global digital business division asked "Most people, I think, don't even know what a rootkit is, so why should they care about it?"[23] He explained that "The software is designed to protect our CDs from unauthorized copying and ripping and Rootkit technology is one of the best ways to do just that.""
