Very easily...

Nope, just nope.
ONLY with a program, that is deliberately developed to break the copy-protection, is ist possible, to break /circumvent the protection - and if you use that program, you can hardly pretend afterwards: "well, I didn't know, I would be circumventing the copy-protection!"

Any judge worth his money would ask you, why you used that program in the first place.

After all - if you're really so "unwitting", you surely would've first tried to just "copy/paste" the DVD/BR content, no?

And since that isn't possible, you then would have to look for a program, of which you know in advance, it will provide you with the possibility of breaking/cicumventing the copy protection.

And to do that - you have to inform yourself, first.

In which case, the ice you're skating on, is so thin, that - legally speaking - it's non-existent.

That's incorrect.

For instance, if you try to copy/rip copy protected audio CDs, it depends entirely on the CD player whether the copy protection works or not. If it doesn't work, you can copy the CD exactly as you would copy an unprotected CD. If it works, well then you need to actively try to bypass it by using some special software or something.

The same can be said of DVD rippers, although I guess with those the default thought is that they are created to bypass copy protections. Anyway, a technologically less experienced person really can't tell what happens when using those programs, the programs simply copy the disc content to some other place and only some cryptic messages may or may not indicate whether some kind of protection has been bypassed.

To confuse things, sometimes discs without copy protection have copy protection text on the package. On the other hand, sometimes copy protected discs don't contain messages about copy protection (although in those cases you are able to return it and get a full refund, ironically...).

What makes this kind of problematic is that for instance copy protected CDs are not really CDs!!!
They are marketed as such, and can be found among real CDs, but I have a couple of audio CDs which actually don't have the usual Compact Disc symbol anywhere on the package, but simply have Copy Protected symbol where you normally would find the Compact Disc symbol. That's because they use technologies which is not part of the Compact Disc specification.

It can be argued what customers are supposed to be doing with these? CDs are being played by a CD player. "Copy Protected" should logically be played by a "Copy Protected" player then? If you are trying to play a disc which isn't a standard CD in a CD player, when exactly are you crossing the line for proper use?

This is what I meant. Additionally programs that "accidentally" can break copy protection are sold in stores or can are just one Google search of "copy DVD" away. Users who are not tech-savvy can easily use applications that remove copy protection without ever knowing.
