Interview with Alexander Noe, PxScan Developer
wikinerd writes "I interviewed Alexander Noe, developer of the open source PxScan and PxView utilities. He recently received a cease-and-desist letter by Shinano Kenshi, the Japanese company which controls Plextor. His utilities provide similar functionality with PlexTools, sending special command sequences to Plextor DVD recorders that activate special features such as media quality check."
It was already slow for me:

The interview was completed through IRC chat. The whole text is released under a "verbatim copying" licence, so we encourage you to re-publish it if you wish (see the full licence at the end).
Nikolaos S. Karastathis: Hello, please introduce yourself and briefly describe the utilities you developed.
Alexander Noé: I'm Alexander Noé:, currently studying computer science at TU-Chemnitz. The utilities PxScan/PxView i've developed perform error scans on Plextor PX-712/716 and Plextor Premium drives. The tests are the same, but PlexTools had some handling I didn't like, for example you can run several tests on DVDs, but in PlexTools you couldn't trigger them at once, but rather had to trigger one test at one time. My goal was just to make all that more convenient.
Nikolaos S. Karastathis: You received a letter via email about these utilities. Who sent the letter and what did it say?
Alexander Noé: The letter was sent by lawyers working for Shinano Kenshi. The Lawyers claim those utilities would violate their clients rights.
Nikolaos S. Karastathis: Have you replied to this letter?
Alexander Noé: No, I haven't.
Nikolaos S. Karastathis: Why do you think the lawyers sent this letter, and what are their requests?
Alexander Noé: Plextor maybe sees me as competitor. However, they don't offer any Linux version, neither free nor for money, so I have absolutely no idea what their problem with pxlinux could possibly be. They demand that I cease-and-desist from any further infringements, and demand that I comply a list of all steps I've taken to ensure that their clients' rights will no longer be infringed.
Nikolaos S. Karastathis: Have you contacted a professional lawyer yet? Did you receive any legal advice?
Alexander Noé: A professional lawyer said that in his opinion, none of the accusations made by Shinano are justified.
Nikolaos S. Karastathis: Is the letter confidential, can you post it for everyone to see?
Alexander Noé: The letter itself is not explicitely marked as such, but I'm not sure if I have the right to publish an email sent to me in general without the sender agreeing on this.
Nikolaos S. Karastathis: In the last years there are increasingly more legal problems for free/libre/open-source software projects. Now software patents may be introduced in Europe. What are your views on this issue?
Alexander Noé: I *really* hope that software patents will not be introduced, but I can't do much about it... as I don't really understand lawyer and politician language, like most people, I can hardly assess the consequences software patents would cause, but it wouldn't make life of free developers easier.

Nikolaos S. Karastathis: What do you plan to do now?
Alexander Noé: I'm waiting what will happen....
Nikolaos S. Karastathis: Anything more you want to say?
Alexander Noé: Considering that Plextor did, not long ago, announce that they would be supporting open-source, I really wonder what all this is supposed to be about. Either they support open-source, or at least "tolerate" it, or they don't.
Nikolaos S. Karastathis: The interview appears to be finished. Thank you very much!

Plextor may be doing a couple things. First and foremost, they're making sure no unauthorized Open Source projects spring up. They have no interest in supporting the software unless they wrote it. I can understand this motivation. We all remember the Mandrake Linux release that killed some CD RW drives, and Plextor is no doubt concerned about a similar problem for them.
Plextor would have nothing to fear if they've followed the ATAPI / MMC specifications correctly. Those drives that died (I had one) implemented something like a firmware flash (or "trash") command using the same opcode as the write cache flush command (or something similar, the details in my head are fading). On a CD-ROM drive, write cache flush obviously is unnecessary, however, that doesn't mean that the opcode can be grabbed to be used for something else. The CD-ROM manufacturer was the root cause of this problem.

As mentioned in this /. article, Plextor PVRs Now Support Linux
Plextor Press Release, March 8, 2005
Plextor PVRs Now Support Linux
"...Plextor is strongly committed to supporting the Open Source Software movement with free development tools that help speed the creation of next-generation Linux-based video software," said Dirk Peters, director of marketing, Plextor. "The release of this SDK was a direct response to requests from the user community for an easier way to work with Plextor ConvertX video capture devices on computers running Linux..."
"Plextor's new Linux SDK provides developers with a free GPL-based full-source driver to support all of the popular V4L2 applications," said, Tom Luax, vice president of sales, WISchip International. "The combination of low-cost MPEG4/DivX Video compression hardware and Linux OSS software is a great solution for anyone who wants to build a high-quality and low-cost personal video recorder for their PC..."
Yes, I realize this is for PVR stuff, not DVD burners, but one would think their strategy would be a bit broader than product-by-product. Maybe they think their PVR offerings need more help, while their DVD burners don't.
