Looking for more out of your DVD movie purchase other than the movie itself? Then this update about Sony offering digital copies within its own DVDs should interest you. Digital copies are simply that - legal copies of the film that you can easily watch on your PC, PS3 or PSP with almost no hassle whatsoever. Almost. Check out the full details after the jump.

Headplay is probably every couch potato's dream. Imagine a TV. Now imagine being able to take it anywhere and everywhere you go (except perhaps in the shower), and being able to watch movies or play games on it anytime you want. That's the concept for the new "Personal Cinema System" device, Headplay.

Headplay is a head-mounted device; basically, a TV you wear on your head. You can connect it to your gaming consoles, your DVD Player, your iPod, your PC, and maybe your Betamax player if it hasn't choked on dust yet. If it has a video out function, Headplay can most probably display it. You can also plug in a memory stick and Headplay can run the media files - movies, videos, and images - with its own built-in player.

Once you're behind the lenses of Headplay it's pretty easy to just relax and go dead to the world around you. It's nothing but you and the screen, with the stereo sounds blocking off everything else. It's like your own movie screen inside your living room.

Here's a bit of news that the more tech-savvy of us should take note of: the software included in high-end memory sticks sold by electronics and media giant Sony Corp can make your personal computer vulnerable to outside attacks. This alarming bit of info comes from none other than researchers from two security firms.

So what's the actual product from Sony that's been causing all this hub-bub? Specifically, the MicroVault USB memory stick and fingerprint reader. These two products seem to have software that creates a hidden directory on the computer's hard drive.

This hidden directory is known as a root kit, and it pretty much opens your PC up for hackers to exploit and take advantage of - all with you none the wiser.

It doesn't end there: not only is the root kit undetectable by normal means (searching through your folders, browsing through your directies) - it's also hidden away from some of today's more popular computer security software, or those programs you use to sniff out viruses, spyware and other sorts of malware.

This is definitely not good, as it's not only a very real vulnerability, but one that's practically permanent (barring a full hard drive wipe). And this recent finding by F-Secure, a Finnish security software maker, has been confirmed by none other than McAfee Inc.

What can be done, then? For now, you might want to beef up your computer's security measures, if you've been using the aforementioned devices, and hope for the best - as well as cross our fingers that Sony quickly catches wind of this and resolves the issue as soon as possible.
