    The amount of engineering that went into this feature stack is insane. Maybe instead they could figure out how to make high quality content reliably easier to stream than to pirate…

      It already is. The problems of streaming come from capitalism, not technical difficulties.

      Right? I don't get why they do such rocket-science copy protection when you can always point a camera at a TV, or snoop the bus going to the actual display panel or something.

    Once again, legitimate users get the short end of the stick. Owning things seems to have gotten out of fashion as well in the age of remote server dependent playback.

    I still have some sealed HD-DVDs, hoping they might be worth (literally) a few dollars one day. lol
    I personally thought HD-DVD worked a bit better than typical Blu Ray disks/players of the time.
    The menus and extras on HD-DVD were often a bit nicer.
    The menus on Blu Rays seemed to be more sluggish.
    (that could have been partly due to the player at the time. I was using an Xbox 360 with HD-DVD drive. Then an LG Blu Ray burner in the PC a few years later.)
    I don't know much about the encryption stuff, but it's always interesting to hear how it got broken.

    It is funny how many drives just die hours before a presentation on these conferences. This is the 6th video I binge with a dead drive.

      The demo gods are the only gods that exist. I don't know why we haven't started worshipping them yet. Manually corrupt one slide of your presentation to appease them and avoid their non-deterministic wrath.

      This is why I use high endurance micro SD cards on my Pis. I learned this lesson the hard way too many times.

    DRM is awful for honest buyers!
    I've been bitten by it for at least once and I hate it.

    So... I own exactly ONE UHD Blue-Ray, and I specifically bought a suitable DVD drive to go along in 2017 when that stuff was new, imported it from the US as it wasn't even on the market in Germany at the time.
    I placed it in my I7-7700k system, used it a single time to watch the movie because it turned out I had to use the IGPU to hook up my TV due to DRM issues with my graphics card ( i guess the idea was if the media content is played out to a monitor via a video card it could be captured along the way and rerecorded) and that was a hassle.
    Now I find out that once this system dies and I need a new CPU, both that BD and the drive are going to be paperweights I will never be using again to watch said movie because Intel dropped a required feature for those DRM shenanigans after it got broken and abused.
    Cool beans.
    Anyone interested in buying a once-watched UHD Bluray of "Solo - a Star Wars Story" ?

    • @dascandy

      No, they're not paperweights.
      You'll just have no officially sanctioned software to play it with.
      But you can use VLC to play it regardless. And expect more software to come.

    The unfortunate side of this is that it is one more nail in the coffin for physical media. If studios and producers don't feel safe releasing content on physical media, it's one more reason for them not to. I was quite content with being able to rip blu ray but watch 4k as intended from disc. I will be super disappointed if this brings the demise of new releases on 4k uhd blu ray.

      Well, the big companies need to understand that they can make huge bank by just trusting the consumer. They expect the consumer to "trust me bro", so them doing the same should be reasonable...

    Well, the content industry is pretty much removing any further development of physical media, so this is just more justification for them to move to streaming only.
