I knew I should have searched. Thanks.

I'm getting an error with the Criterion Okja UHD. "The volume key is unknown for this disc - video can't be decrypted failed to open disc". What causes this? Is the title too new?

Unfortunately, this is a problem with the disk - your drive can't read parts of it. It's possible that cleaning and waxing it may help.

I'm thinking it's probably the same issue, but I went ahead and posted my other problem disc, Forbidden Planet. When you say waxing, do you mean literal waxing ...

I included both of these in the same post because they are on the same disc. Same problem as my previous Christmas Story post, I can rip everything from the disc except these two titles.

And sometimes, rearranging how the pieces of the file are multiplexed together can make a big difference; When creating MP4 files, Handbrake gives an option to optimize the multiplexing for lower-bandwidth connections ("Web optimized"). I think the merge tool in MKVToolnix has that, but I have not ...

If the artifacts come and go, that's not a file problem, but a bandwidth problem... Either the data isn't getting to the player fast enough for it to render, or the player isn't getting enough processor time to do the decoding. Sometimes it is both.

If I'm doing a handbrake encode, my CPU stays ...

I have always tried to use SMplayer it has never given me a problem. Perhaps you can try it and report back.


I found a version of Mplayer and that seemed to work with only minor artifacts popping up occasionally. It's not the main movie so I can live with that. Ultimately I would like to convert ...

Blocky playback can describe several problems. One of which is issues with BD+ translation, but your log do not contain the portion where BD+ error messages would be displayed.

However, it can also describe the drive not supplying video to VLC fast enough. If you pause VLC, and back it up over a ...

I recently discovered a problem with a few discs having choppy playback with blocky artifacts in VLC after ripping to .mkv. This only happens with the special features on Batman Returns, Green Zone and Charlie and the Chocolate Factory. All playback is fine in a set-top player, no scratches on the ...
