Are you doing a Backup or Open/Save as MKV? Sometimes Backup works when Open doesn't, and vice-versa. With a backup, you can open it later with MakeMKV and save as MKV files, assuming the backup completes. I have had a few disks that have navigation anomalies that required tweaks of the program by M...

On BD sources, MakeMKV does a checksum of the files and tests it against the checksums on the disk; it is unusual for something to pass that process and have a glitch like you describe. Not impossible, just very, very unlikely. If you play it in both, does the glitch occur in the same frame? Near a ...

Hardware tracking errors are at the drive level. It's trying to follow where the disk tells it to go and it can't get there.

If it happens at the exact same point in multiple disks, I'd suspect the drive is having issues seeking, or possibly switching layers (focus issue).

Yes, you will. Fortunately, they're not that expensive anymore.

They get a bit more expensive if you want to get ready for UHD video, but regular bluray drives are under USD 50 many places.

If the glitch moves around on playback, it's more likely a problem with the player than the file. Or, more precisely, the player cannot deal with the bandwidth different sections require.

First thing - MakeMKV is not a "copy utility" for disks; it's primarily for convert (ripping) titles off of optical media to your hard drive. Even its Bluray "backup" function will not produce a file that can be directly burned to a blank Bluray disk. THAT requires BD authoring software, and a BD bu...

Given that the release version is the same as the last time you asked, the answer would have to be, "There is no news." Are you certain that the GUI isn't just making repeated calls to the CLI, one file at a time? It is communicating with it bi-directionally, so that it can display progress, after a...

More information is necessary. There are lots of things that can affect bluray ripping, from a dirty disk to a new version of AACS that has blocked your drive from reading BDs. At this point in the conversation, though, there is no way to tell. We've even had people try reading BDs in a DVD-only dri...

MakeMKV uses a "default rule" to select audio. Usually, people complain that the default rule selects the descriptive track instead of the "normal" tracks. You can change that rule to deal with things like this, where a track you want might be ignored. But you must first enter "Expert mode" (Prefere...

Alien subtitles only are in subtitle track 4. All English subtitles is track 1.

The player itself determines half of whether or not "skip to next" will work. In MKV files, you typically have a chapter track; if the player supports it, it will work, but if the MKV file didn't have one to begin with.... MakeMKV cannot magically make one. There are chapter editors out there that w...

Using a backup, if it's been decrypted already, you can navigate to the BDMV/index.bdmv file and open it.

So, if you start multiple copy operations between the drives, the aggregate speed never drops below 700 MB/s? That's highly unusual. I see degradation in overall copy speed even with a dedicated processor handling the drives, when multiple streams are involved. If it were an SSD array, the affect of...

It will depend upon how much buffering your drive system does. Remember that raw throughput does not take into account directory updates, and if you are not writing a contiguous block of data, the array has to update the file system's directory. Even with buffered writes, the operating system is goi...

I've done 5 anime series and one movie with subtitles in the last week using 1.12.2 and handbrake found all the subtitles. So it may just be a selection rule issue.

Have you verified that the subtitles were selected prior to the rip?
