Anything we can get towards working DVD is good. On Tue, 26 Oct 1999, Syam Gadde wrote: [...] Basically, my modifications follow the publicly available Mt. Fuji spec for Multimedia Devices (SFF8090), and allow a user-level program (such as css-auth above) to do the nasty work, using ioctls to drive the authentication process. Note again that this addresses only authentication, not the meatier problem of decryption. Is SFF8090 available online somewhere? So if there is interest, and if no one has done more extensive work on this, I'll clean up my code and post patches. -syam To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: CSS authentication for DVD-ROMs
I agree. I have a Creative Labs Dxr2 DVD kit that I'm more than willing
to test code on/with. (Any word on the Dxr2 mpeg decoder card? )

Re: CSS authentication for DVD-ROMs
Patches for CSS to a bleeding-edge -current (well, Monday night) can be found at: http://www.cs.duke.edu/~gadde/freebsd/dvd/ Anyone want to try it out? Run "tstdvd" on a patched kernel and see what happens. I've been able to authenticate most of my 6 DVDs (including The Matrix and A Bug's Life), but my "regionless" DVDs do not, surprisingly. I am investigating. I'm using a Toshiba SD-M1202 DVD-ROM. Oh, and by the way, do not run the dvdinfo program in the css-auth package unless you want your DVD drive to be unusable until your next reboot. -syam To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
