Protect DVD-Video prevents discs from playing on your PC
Here's something that opponents of restrictive DRM implementations aren't going to be too happy with: ZDNet is reporting that new copy-protection software for DVD publishers from a company called ProtectDisc not only makes it difficult to rip movies that you've purchased -- no surprise there -- but actually prevents discs from playing in a Windows PC at all. So if you pop in a DVD "infected" with Protect DVD-Video, it can't be read by Windows Media Player, Media Center Edition, or any DirectShow-based software, thanks to a Universal Disc Format that tricks your machine into believing that the IFO file is zero bytes long. As you might expect, there are already workarounds out there that can bypass Protect DVD: SlySoft reportedly updated its AnyDVD software recently as a direct response to this protection racket. Still, this is a discouraging development for home theater buffs who have upgraded their setups to revolve around a hot new HTPC; remember that old standalone DVD player that you stuffed in the attic a few months ago? Well if Protect DVD and other tools like it take off, you may have to dust off that old player and return it to its rightful home in your gear rack.[Via PVR Wire]
TiVo Series3 and JVC receivers throw DRM fit
Wouldn't you know it. After paying for anger management sessions to deal with those repetitive delays, finding out it wouldn't work right with your shiny new plasma, and wondering if the thing was even worth the $800 to begin with, we've got yet another reason to pass on TiVo's almost-excellent Series3. If your box hasn't been plagued with issues just yet, we sure hope you aren't the proud owner of a JVC receiver, or you could be facing more of those ever-present DRM snafus. During CNET's testing of the Series3 box with the JVC RX-D702 receiver, things were going perfectly smooth as the TiVo streamed video / audio to the JVC over HDMI, and separate monitors via composite / S-Video -- until they switched over to HBO HD. Programming on this channel, as well as HDNet and Universal HD, yielded a gray screen complemented by a (presumably enraging) message stating: "Viewing is not permitted using the TiVo Digital Media Recorder. Try another TV input." Further investigation (read: hitting the "Info" button) spilled the beans on the DRM-laden troubles, as testers were greeted by a statement declaring "regulations of the copyright holder" the villain. While the "glitch" would probably be a non-issue had TiVo included TiVo To Go on the Series3 boxes, the almighty media providers would have none of that, and currently, the problem can only be solved by swapping out your (presumably costly) HDMI-equipped receiver for another brand. Chalk another one up for the content guardians. [Via Thomas Hawk]
Embedded RFID to smack-down DVD piracy
Privacy types are just going to love this one. Major studios, including Warner, Disney and Fox, are prepping to start embedding RFID chips in every DVD produced, enabling them to track the disc from the factory to the store to your home. The chipped DVDs will then be examined by your home DVD player to make sure you're not trying to do anything fun like playing the movie in an incorrect geographical region, or running a copied disc. While they're starting out with DVD movies, it seems the proprietors of the tech are hoping to squeeze the chips into HD DVD, Blu-ray and any other medium in need of some copy protection. "This technology holds the potential to protect the intellectual property of music companies, film studios, gaming and software developers worldwide," sez Gordon Yeh, CEO of Ritek, whose U-Tech subsidiary is all prepped to start making the discs in Taiwan. Once all the manufacturing kinks are worked out, U-Tech will work with the studios for a test roll-out in Australia. Of course, to make any of this relevant, new DVD players will be required, but we're not clear if the discs will play as normal on non-RFID players. So, we're still short on deets, and there's no real word on when we can expect any of this to show up on Wal-Mart shelves, but that doesn't mean we can't start running around frantically and start decrying the end of our civilisation, for it is indeed at hand.
Xbox 360 HDMI cable still a possibility?
Just when we were getting used to the reality of no digital video outputs for our Xbox 360s, a hardware manager for Microsoft has re-stoked the rumor fires. Despite the claims of some that such a cable may not technically be possible, the FiringSquad quoted Microsoft's Rob Walker as stating that the company is "still discussing" what to do if movie companies begin to restrict high definition playback to digital outputs only, that they are "looking into" making an HDMI cable for the Xbox 360, and of course another no comment on the price of the HD DVD add-on. The remarks came during a panel discussion at the Gamefest conference where Microsoft also announced tools to allow users to make their own games. At this point we don't know what seems more (or less) plausible, that Microsoft is willing to sell a device even if by their own admission they don't know if copy protection could soon render it useless -- a potential weakness for the cheaper Playstation 3 variant as well -- or they have an agreement in place to guarantee analog outputs will continue to work for some time and this is all just subterfuge.
Sony ponders destruction of used game market [Update 1]
The technology to prevent playing unlicensed software has been patented and should be delved a little deeper into. Let's face it -- we probably buy most of our games used. Heck, we spent $990 million on used games last year. Sony's new technology registers our games when we load 'em up and prevent any other system to play them. It even prevents any other copy of the same game to be played. Scratched up your copy of your favorite game? Oops, you can't buy another one because it won't work. So very, very sorry.That seems a bit extreme. Perhaps there will be ways around it or perhaps it won't be as harsh as the story at 1up.com makes it out to be. Sony could be sharing what the patent has the ability to do, but won't necessarily utilize every feature. Still, this may cripple our used game market or at the least hinder it. If anything happens, let's hope it's something like a timestamp feature on games so we won't find a used game at a lower price two days after the game's release. That gives the developers and publishers more time to make money and keeps the bargain-hunters waiting for a few weeks. One month wouldn't be too long to wait for a game to appear used, would it? What does everyone think? Should there be a timestamp on games, full protection, or none at all leaving doors open to piracy and whatnot?[Update: after a comment, the URL with the patent is included to stop the "fake news" nonsense]
Security hole found in early HD-DVD software
We all know that HD-DVD and Blu-Ray movies will be chock-full of anti-piracy measures, but it looks like one glaring hole didn't get plugged: Computer magazine c't has discovered that the first software players running on Windows XP allow screenshots of the movies to be created in full resolution. To do so, you only need to press the Print key on your keyboard while the movie is running. Such a screenshot function could then be automated to produce copies of HD movies both from Blu-ray Discs and from HD DVDs picture by picture. As c't calculated, the performance of current PC systems is sufficient for a clean recording using this procedure. Once a pirate has all of the individual pictures, they can be put together to create a complete movie and mixed with the audio track that is grabbed separately. This copy protection hole affects both Sony's first Blu-ray PC Vaio VGC-RC 204 and Toshiba's first HD DVD notebook Qosmio G30. Both of them use special OEM versions of Intervideo's WinDVD player software. It's amusing that the powers-that-be would miss something so obvious as the good ol' print key. You'd probably be more interested in this news if your console was mortally tied to the success of a certain format.
Security flaw allows HD flicks to be copied with screencaps
With all of the time and money that Hollywood and the consumer electronics industry have poured into copy-protecting high definition content, we were amused to learn that both formats can already be duplicated by the simplest of means: the trusty Print Screen button on your keyboard. UK-based Heise Security is reporting that the special OEM version of Intervideo's WinDVD software bundled with both Sony's first Blu-ray Vaio and Toshiba's first HD DVD Qosmio contains a security hole that allows users to capture video frames at their full resolution by simply triggering that Print Screen option -- which in and of itself is little more than a curiosity, but opens up the possibility of running a script that advances a given film one frame at a time and automates the whole screencap process, which would allow pirates to create high def copies by compiling the pictures and dubbing in the audio. Toshiba is already aware of the "problem" and claims that an impending software update will provide the fix, but as one HDBeat commenter astutely pointed out, as long as you can see a picture on your monitor or hear sound through your speakers, there will always be a way to capture that data.[Via HDBeat]
Princeton professor sez cracking HDCP is "eminently doable"
It seems that HDCP, the high def content protection scheme that's all the rage among Hollywood types, may not be as secure as the suits had hoped: Princeton University computer science professor Ed Felten takes a look at the standard's supposedly well-known security flaws and dumbs down the basic tech on his blog so all us non-math majors can understand. Basically, HDCP relies on a handshake between connected hardware wherein the two devices send each other a set of rules to be applied to the forty-or-so numbers that constitute both devices' "secret vector" -- if each device reports the same numerical result (as the pre-determined mathematical rules dictate they should), sweet high definition content can begin to flow freely. According to Felt, all it takes to figure out a given device's secret vector or create a workable "phantom" vector is to perform a number of handshakes equal to the number of elements in the secret vector, followed by a little bit of algebra to tease out the results from a matrix of equations (follow the "Read" link for a better explanation). Although HDCP-restricted HDMI and DVI connections aren't prevalent enough yet for anyone to have actually undertaken this project (either that, or fear of legal reprisals has kept any successful cracks from being published), the simple fact that it's doable could mean nightmares for Tinseltown sooner rather than later.[Via Boing Boing]
What if the DRM on your DVD player didn't work?
Yeah that might make you happy, but it could be a real problem for the manufacturer. Enter Samsung's DVD-HD841, an upconverting DVD player sold in 2004; it didn't sell well until a key "feature" was uncovered, you could hack it to turn off region coding and HDCP protections. The player has long been off the market, but now several movie studios have brought lawsuits against Samsung for their failure to protect content.But we all know that there have been ways around the CSS encryption practically since DVDs launched, so why sue now? Ars Technica supposes that this is more about setting an example for the next generation of DVD players, and I tend to agree. If/when someone finds a way around AACS and HDCP expect the lawsuits to come hard and heavy.
HDMI to add more features
They're not stopping at version 1.2, HDMI's Licensing group today announced that they plan to add more features to the specification in the coming year, while maintaining backwards compatibility with existing devices (believe it when I see it). In addition to the tighter relationship with PC's via the newly announced UDI connector, they expect to support greater color depths (30, 36 and 48 bit), higher speed connections, a new mini connector for cameras, a/v synchronization and new audio formats like Dolby TrueHD and DTS-HD.
