Over the last couple of months, there have been reports of HD-DVD and Blu-ray copy protection being defeated and bypassed. I can’t say I’m an expert in this area and I haven’t slogged through the public AACS documents. While it’s unclear if these methods (and keys) are temporary “solutions” or if they will permanently bypass AACS, one hacker describes his methodology for teasing out the data:
This gave me an idea: what I wanted to do is “record” all changes in this part of memory during startup of the movie. Hopefully I would catch something interesting. In the end I did something a little more efficient: I used the hd dvd vuk extractor and adapted it to slow down the software player (while scanning its memory continuously) and at the very moment the Media Key (which I now knew: my bottom-up approach really paid off here) was detected it halted the player. I then made a memdump with WinHex. I now had the feeling I had something. And I did. Not surprisingly the very first C-value was a hit. I then checked if everything was correct, asked for confirmation and here we are.
After spending time with all three next-gen gaming systems, I finally decided on picking up a Xbox 360 last November. At the time, Micro Center’s deal seemed too good to be true ($200 for a $400 system) and involved playing Rebate Roulette. Fortunately for me, I won — in about 10 weeks I received two $100 checks. That one above just arrived today, actually ahead of when they had promised.
Knowing what I know now, I would have gladly paid full price for the 360: Xbox Live is so well executed and the new video downloads are a keeper (even if they use fake Microsoft currency and the selection is thin). Maybe I’ll just dump that bonus $200 into a HD-DVD accessory… Hm. Or perhaps I’ll apply it to a Wii when some interesting games come out this spring.
I was wrong. Just a few weeks ago I speculated that we wouldn’t be able to purchase a next generation hybrid disc player in 2007. Heck, I even saw a glass enclosed model at CES but refused to believe it would make it to retail any time soon. But the rumors started that LG Blu-ray HD-DVD hybrid players (BH100) would be available at Best Buy 2/4, then a unit showed up in someone’s home, and yesterday Gizmodo posted a hands on review.
I had figured this project (and others like it) would be derailed, that to sell a device like this a vendor would need endorsements from both consortiums — something I didn’t see happening this early in the game. However, it looks like the player is in stores despite the lack of support for many HD-DVD interactive features. I suppose Toshiba’s HD-DVD camp could try to block this, but I dont’ see them stuffing it back into Pandora’s box.
Reports today indicate Canon will buy out Toshiba’s stake in their joint SED flat panel display business. The hope is that this will clear the way in a patent dispute with Nano-Proprietary, who asserts their technology is licensed solely to Canon. The ongoing tiff prevented SED sets from making an appearance at CES this week.
