From http://www.asahi.com/english/Herald-asahi/TKY200709060062.html today:

Film producer Norio Tsuchiya was trying to figure how to get his new movie with a strong social message to reach a wider audience when he came across new DVD technology.

He learned the technology provides password protection for DVDs. That way, Tsuchiya reasoned, he could distribute the new film in a format that was easy to duplicate, with a secure copyright safeguard.

And so on Sept. 1, the movie "Zero Karano Kaze" (Wind from zero), which tells the story of a mother who lost her only son in a drunken driving incident, was made available for rent in a DVD format with copyright protection.

The password function enables the copyright owner to limit the number or duration of viewings by a customer.

The movie's distributor set rental fees for the film based on the anticipated number of viewers. The cost is 400 to 500 yen per adult and 300 yen for high school students or those younger.

The new system is expected to secure profits while taking films with social messages, many of which are usually screened in small theaters, to wider audiences.

"A movie shown at a small number of theaters will get wider distribution while its copyright is protected," said an official of Visionare Corp., a Tokyo company that patented the technology.

In "Zero Karano Kaze," veteran actress Yoshiko Tanaka plays the mother, based on the story of Kyoko Suzuki, 58, of Kanagawa Prefecture. Suzuki lived with her only son, Rei, after her husband died.

In 2000, Rei was killed by a drunken driver with a history of driving under the influence and without a valid license.

Rei was 19 and had just entered Tokyo's Waseda University. The Chinese character for his name also means "zero."

Suzuki led a nationwide campaign, through an exhibition titled "Inochi no Messeiji Ten" (Exhibition of the message of life), for tougher penalties against traffic offenders.

The movie opened in May, mainly at small theaters or gatherings. Around that time, Tsuchiya, 56, learned about the new technology, which allows a customer, for example, to pay for a password that provides access for two weeks.

Tsuchiya asked Visionare, a digital media technology developer, for cooperation in making the DVD.

The film's director, Toshi Shioya, 51, said: "I believe this movie has the power to make the audience think they must not drink and drive."(IHT/Asahi: September 6,2007)


Is this another DIVX? ...does anyone know how this 'password protection' works? The http://www.visionare.co.jp/ website is in Japanese (which I can't read.)

Surely this is impossible for DVD players, since they have no way of saving info or writing to the disc?
How secure is even password protecting for a one password always works method, even that is just 'hiding' isn't it?

I'm not so sure this company is peddling a simple hiding mechanism (with static per-disc 'passwords'.) They claim their "DVDMAGIC" enables some sort of time-restricted viewing. It's hard to say with just a machine-translation at hand.

In addition to this, the website also seems to promote a plain-vanilla sort of copy-protection called "Magic Guard for DVD" or perhaps "ACCS-Tech". Doesn't sound like anything special, that.

For standard Video-DVD compatible discs nothing like this is possible. Unfortunately the article doesn't mention how these “protected” discs are supposed to be played back. But at the end of the day it can only be YADS: yet another DRM scheme.

Maybe they plan to have you input a password at the menu, using the remote? :P

Mere passwords? Could these actually be "PC-friendly" discs?
Meh, nothing that can't be defeated in under 10 days, if 3 don't suffice ;)
