Does anyone know if you can "re-encrypt" BD+ by using different key sets or other advanced methods to make previous cracking methods (temporarily) ineffective on new disc releases?]]></description><dc:creator><![CDATA[TrentD]]></dc:creator><pubDate>Nov 19th 2007 3:44PM</pubDate></item><item><title><![CDATA[Comments on Macrovision purchases BD+ DRM for $45 million]]></title><link>http://hd.engadget.com/2007/11/19/macrovision-purchases-bd-drm-for-45-million/</link><guid isPermaLink="true">http://hd.engadget.com/2007/11/19/macrovision-purchases-bd-drm-for-45-million/</guid><description><![CDATA[Yes, you can. Unlike the security scheme in HD DVD, BD+ is renewable. It can be broken, but fixed. Windows Media format files do something similar, and WMV has been broken many times. Every time it is, Microsoft releases new updates to secure future playback. Similarly, each Blu-ray disk carries the virtual machine software package on it necessary to decrypt itself for playback. If BD+ is broken, this just means you can decrypt any Blu-ray disk that currently exists, but not any future releases (or future copies of current movies).<br><br>It has yet to be proven if SlySoft's AnyDVD will work on future Blu-ray releases.

The Blu-Ray spec probably requires it. If Macrovision owns the technology then they can license it and make a certain amount of money every time a disc or player is sold.]]></description><dc:creator><![CDATA[JimJ]]></dc:creator><pubDate>Nov 19th 2007 4:22PM</pubDate></item><item><title><![CDATA[Comments on Macrovision purchases BD+ DRM for $45 million]]></title><link>http://hd.engadget.com/2007/11/19/macrovision-purchases-bd-drm-for-45-million/</link><guid isPermaLink="true">http://hd.engadget.com/2007/11/19/macrovision-purchases-bd-drm-for-45-million/</guid><description><![CDATA[I wonder how much this DRM costs vs how much additional revenue it brings in.

There is absolutely no evidence or proof that the Slysoft program has hacked BD+.  From what I understand BD+ is renewable so if one movie gets hacked the next release closes the hole.  It also retards playback of any copied discs if you get that far.  Who has the time and patience for that?  Just steal the disc from the store if you don't want to pay for it.]]></description><dc:creator><![CDATA[butterknife]]></dc:creator><pubDate>Nov 19th 2007 6:27PM</pubDate></item><item><title><![CDATA[Comments on Macrovision purchases BD+ DRM for $45 million]]></title><link>http://hd.engadget.com/2007/11/19/macrovision-purchases-bd-drm-for-45-million/</link><guid isPermaLink="true">http://hd.engadget.com/2007/11/19/macrovision-purchases-bd-drm-for-45-million/</guid><description><![CDATA['that went from "impenetrable for 10 years" to "cracked" just last week.
