Thx, it works well, but can dvd+rw-mediainfo /dev/dvd identify a kind of protection mechanisms?

[julian67]

Code: Select all

man dvd+rw-mediainfo

will tell you this much quicker than asking on the board. No.

under man dvd+rw-mediainfo I cannot find about a protection mechanisms.

[julian67]

That's what the "No." means in my previous post. If it's not described in the manual that's because it's not a feature.

Is it any other tool to find out the kind of protection mechanisms?

Yes. Not completely free software but it runs quite well on Linux even though it's a beta.
