I searched C|Net and news.com and only found a couple token mentions of AACS. This is the new copy-protection scheme being adopted by both HD-DVD and Blu-Ray.
According to this site: http://www.dvdsite.org/, there may be some scary elements to AACS, including the ability to render your discs or player unusable if one of their magic keys is compromised, as happened with DVD and DeCSS. Click on the FAQ link for full details.
Once again, this sounds like Hollywood is going too far in the name of copy-prevention. The above site suggests that a mechanism to replace obsoleted discs and upgrade player firmware would be sufficient, but I'm thinking, "what if I have some small-studio production or out-of-print material that's been decommissioned a couple years after I bought it? Who's going to replacew that?"
I'd like to see C|Net or someone shed more light on this concern so that more people know what's coming. If that website is wrong, great. If they're right and people don't know, then we need to get the word out so that people can make an *informed* decision about what they're buying. Or not buying, as it would be in my case.
Cheers!
