    Has anyone tried successfully playing back decrypted Blu-rays (the back up discs that some of us make to keep our original store bought discs in pristine shape) on any of the new Blu-ray players lately?

    My process is:
    1. I use MakeMKV to produce unencrypted BDMV and Certificate files
    2. I use BD Rebuilder to put those files back together
    3. Then I use Imgburn to create one unencrypted Blu-ray disc that will play in my Blu-ray player.

    I've never had any serious problems playing back a Blu-ray in my Sony GoogleTV Blu-ray player, though on a Sony Playstation the audio would cut out after 20 minutes. That however would NOT happen when we played a Blu-ray on an Xbox. It played perfectly using an Xbox.

    But now I am considering buying a new Panasonic 4K Blu-ray player (the DP-UB820) and I'm wondering if "my process" above will result in Blu-ray Discs that will play correctly in the new player all the way through. Or will I lose the audio after 20 minutes? Has anyone had any actual experience with this lately?

    At one time, I thought that there was something that Blu-ray Player manufacturers were required to install in a Blu-ray player that would stop the audio after about 20 minutes, but I don't know if that is true any more. Can someone wise me up?

    Thanks!

    the audio cutting out sounds like a cinavia issue.
    you would need to use a program such as dvdfab that can repair
    the audio track ( providing the disc is supported, "most are"). so it isn't a issue with your player.

    Thanks guys!! I must really be getting old to have forgotten about Cinavia. But when you mentioned it and I then read the link, it all came flooding back. Using a Blu-ray player that doesn't check for Cinavia, I'd pretty much forgotten about the problem. But with a new 4K Blu-ray player on the horizon, the Kracken has re-arisen.

    DVDFab, here I come! Hope you can handle converting 4K originals into 4K 25GB Blu-rays with Atmos sound and with Cinavia removed! We shall see.

    The product information for DVDFab DVD & Blu-ray Cinavia Removal says nothing about UHD Blu-ray, so try before you buy.

    Plus, assuming it works for UHD Blu-ray, you may need to accept something other than Dolby Atmos. If you read the product information for DVDFab DVD & Blu-ray Cinavia Removal, there is no mention of Dolby Atmos. The best Blu-ray audio format that the product information says this software can process is DTS HD Master Audio, and that is output as a DTS-HD audio track.

    Unless some breakthrough has occurred, it's well established that any "Cinavia removal" program replaces the audio with a version from an non-Cinavia infected disc which is why Atmos isn't supported, there's no alternative track to replace it with.

    Somehow I missed that DVDFab now lists a Cinavia removal product specifically for UHD Blu-ray, DVDFab UHD Cinavia Removal.

    [Edit] It looks like the UHD version can't process Dolby Atmos audio either. It is still appears to be limited to DTS HD Master Audio (output as a DTS-HD audio track) for its highest quality UHD Blu-ray audio option.

    Ditch the standalone player and play the file on a mediaplayer that so far don't have to have Cinavia.

    The majority of hardware media players don't support Dolby Atmos and Dolby Vision, but then again many 4K TVs don't support those features either.

    Popcorn (Cloud Media) and 4K
    Dune
    and quite a few others support Atmos

    whilst there are a lot of very cheap media players out there you get what you pay for really.

    The UHD Blu-ray player LloydS is considering supports Dolby Atmos for audio and HDR10, HLG, HDR10+, and Dolby Vision for high dynamic range video. HDR10 is the default HDR format for UHD Blu-ray, but discs which supply can Dolby Vision are becoming common. Dolby Vision is the better option of the two.

    I said that hardware media players with Atmos and Dolby Vision support are few in number because if LoydS wants a media player that can replace a good UHD Blu-ray disc player for playing commercial UHD Blu-ray backups, then he's going to need a media player with Dolby Vision support as well as Dolby Atmos support. That is a rare combination of features for media players at this point. I can't tell from the specs that I saw whether or not Cloud Media or Dune has a player which supports both. I have not yet seen any other media players that can provide both at this point.
