I don't have a lot of UHD disk in collection and it is the first time it is happening to me...

My Dark Knight Rises 4K/UHD disk would take very long time to do the "Processing Titles" phase. I stopped when I saw it would take 6 hours (and time remaining would still increase).
So, I switched to "backup" mode, which seems to have worked, but I don't know what to do, because I didn't got an .iso file to work with.

Any tips or recommendations?

- How long should Processing Titles last?
- What are alternate method to "backup" then make an .mkv out of a UHD disk?

Once the backup is complete, use the "Open Files" function of MakeMKV and point it to the BDMV file created by the backup. You can then select the titles you wish to process.

Thanks for the tip. Currently opening de .bdmv file... Still a very long process! As I'm writing this, MakeMKV is at 2hr and the remaining still increases.

I don't think I've ever had a backup take longer than 90 seconds to open in MakeMKV. I don't have the Dark Knight Rises UHD, but it seems like something is wrong.

This is what I suspect. It play fine on my PS5, but MakeMKV doesn't like it. I'll delete all files and retry.
