So could you ask the question a little more blunt?
"Gee, I am trying to break a US Law on content protection, would you be my enabler? Don't worry, it only effects the US, and we are in a public forum. Also, do you prefer gray or black in your future pin stripped suit?"
Now if it works in 2.4.18, use it.
If there is a technical issue like loading both ide-cd and ide-scsi on the same device, that is a problem. There have been no changes to ide-scsi in 2.4.19 by me directly. Currently all updates to "stable" are released through Alan Cox, come to think of it so are any releases to "unstable".
Have a little more sense about asking about "copy-protected" media in a public forum, and DON'T !! Regardless if I could answer the question, you have placed me in a position where I can not now.
I should have ignored this and issued a reply.
