With HDR, is the single MKV file created sufficient for playback (on a 4K tv that supports HRD) via Nvidia Shield TV? Do I need an entire backup of the UHD disc?
An MKV is perfectly fine for HDR playback on the SHIELD. Works in Plex, Kodi with no problems. No need to back up the whole disc.
Thank you much for getting back to me so quickly. Off to get a few more discs taken care of!

I'm a little bit confused. In this thread the key files are named as "both KEYDB.cfg and hashed keys are text files" or "KEYDB.cfg or as hashed key". But after I downloaded the file its name is "keys_hashed.txt". Do I need to rename it to "hashed keys" without extension before copying it to the MakeMKV data directory?!

And what is the data directory, "C:\Users\USERNAME\AppData\Roaming\MakeMKV"?

If you note the dates on those discussions, they are VERY old news. Hashed keys are now automatically downloaded, if available, when the disc is scanned.

Edit: I notice this particular thread is a tad long-in-the-tooth, as well.

Thanks. This explains why Planet Earth II was readable ^^

But someone should update the FAQ.

So far I managed to rip about 52 discs (most UHDs and some 3D Blu-rays).

I have encountered 3 failures so far. Thought it was a bad drive but looks like bad discs. What's strange is I had watched these discs in the past in my Panasonic UB820 player without issues. I will be giving all these bad discs a deep clean and retry some of them later and all these discs are US ones (coincidence).
