    But, by default, I would have a limited DVD reader. Maybe I could have
    done it by myself: I don't know. But it wasn't by done default.

    Ha, ha, ha, ha! What a clown!

    For a computer interface, one cannot purchase a DVD reader alone. It must also be a DVD/CD writer (and currently also BDR. i.e. blu-ray).

    On GNU/Linux, there has always been libdvdcss to unlock region codes:

    But then you will withdraw into your standard argument that CD/DVD/BDR
    is no longer relevant in the "modern" world.

    Ha, ha, ha, ha! What a total clown!

    Uh, wasn't the region lock nowadays (read: possibly the past two
    decades?) handled by the *firmware*? Similar to why earlier drives would
    give you scrambled output without "authenticating" with the CSS keys,
    but newer ones give I/O errors? So libdvdcss would do nothing other than
    let you play CSS-scrambled discs from the region the firmware is
    currently set to accept.

    Libdvdcss cracks the encryption (when present) by brute force in
    software. In my experience that can take a while, although I think
    there's some caching ability for next time you play the same disc
    (though I rip such discs so I don't have to bother with it again).
    I think I also had it fail once but that might have been a
    scratched disc. Generally I still try to avoid DVDs from other
    regions, although DVDs marked Region 2 only are often really Region
    2/4 so play fine here in Aus.

    I guess it would only be criminal if decoding the data was an
    offence, and a region-free drive/player would do that without
    Libdvdcss, so no more criminal than using one of those. Or maybe
    it depends on what's considered "circumventing" restrictions.

    I like to paraphrase out loud the unskippable "WARNING" legal
    disclaimers they put before DVDs here about places that home DVDs
    aren't allowed to be screened (come on, how big is the oil rig
    workers' entertainment market really anyway?). "Warning: You are
    watching a DVD! Don't you know you could be fined thousands of
    dollars for watching this DVD? You could go for prison for
    watching this DVD! Jesus Christ what are you doing? STOP!!!"

    Its a fine point when you buy a second hand DVD but want to rip it onto
    a hard disc so its instantly available.

    Any commercial lawsuit would fail, because there was no intent to
    deprive anyone of cash.

    One of the local groups had a fund raiser where they screened Michael
    Moore's 'Bowling for Columbine'. There wasn't an admission charge but they hoped for contributions. Free is good and I was curious about the film. I chuckled when they fired up the DVD with the warning that what they were
    doing was not legal. I was not inspired to make a contribution.

    Those piracy warnings make me want to run up the Jolly Roger but tbh I'm
    too lazy to bother. Netflix DVDs or streaming after they dropped the DVDs
    is easier.
