The txt fle is supposed to be named KEYDB.CFG I thought I read somewhere that computers must have the Intel CPUS after the Skylake genration for to read UHD discs. If so, that could be my issue. I have an Intel i7-6700 Skylake processor. You need the Intel 8000 series chips (I think they were the Skylake X series). The KeyDB.cfg file is missing – Another common reason why Blue-Ray playback fails with this particular errors is if the KeyDB.cfg file is missing from your computer. This file is needed by the libaacs library. In the aacs folder, copy and paste the KEYDB.cfg file that you have copied in the above step. Navigate to the download folder and copy the libaacs.dll file to your clipboard. After that, go to your desktop and right-click on the VLC shortcut and select Open File Location option. . Place the downloaded KEYDB.cfg file in this folder directly. Download Install AACS dynamic library for VLC to use: 2. AACS DYNAMIC LIBRARY. Go to “c:Program Files” Or “c:Program Files (x86)” if running 64bit. Navigate to “VLC” directory, and move the libaacs.dll file into it.

- Read this FAQ.
- Double check that you are using the latest version of MakeMKV.
Posting Guidelines
- If your problem is related to a UHD disc, search this UHD forum for the name of the movie or TV show. If there's an existing thread, add to it. If you don't find an existing thread, make a new thread with the title of the movie or TV show as the subject of the thread. This increases the chance that someone who owns the same disc will see the thread and help you, and it helps others having the same issue to find related threads in the future.
- Otherwise, make a new thread if you have a general usage question.
- Include as many details, such as screenshots and/or MakeMKV's console/debug log, as possible.
- Don't use short and generic thread titles such as 'help' or 'subtitles'. Always be specific in your thread title and in your message.
UHD Basics
I'm new to MakeMKV - what should I do first?
Turn on Expert Mode in Preferences -> General. Expert Mode is really not complicated, and options and functionality being discussed in the forums will make more sense if you have Expert Mode turned on.
Which version of MakeMKV works with UHD discs?
Starting with version 1.10.8, MakeMKV added support for UHD - but you should always use the latest version for important updates and bug fixes. For UHD support, there have already been several new versions with important updates that have made the previous versions obsolete. MakeMKV is frequently updated, so check here for the latest version. If for some reason you want to revert to an older version, you can find some older versions here.
Which drives work with UHDs?
You need a BDXL-compatible LibreDrive drive, which includes most 'official' and all 'friendly' UHD drives. Check out the UHD drives subforum and the UHD Drives Guide thread. (Originally, the drive with the most reported success was the ASUS BW-16D1HT.)
How do I know if a UHD is native 4K or an upscale?
Check this super handy thread! The spreadsheet contains a lot of useful information about UHD releases.
Hashed Keys
How does MakeMKV work with UHDs?
MakeMKV uses Hashed Keys. Originally supplied via a download, MakeMKV now updates automatically. Go to View / Preferences / General and ensure that 'Enable Internet access' is checked.
MakeMKV says that 'the volume key is unknown for this disc'?
MakeMKV produces an AACS .tgz dump file whenever you try to open a disc for which the key is unknown, and will report that the dump has been created. Email the dump file to svq@makemkv.com.
I submitted a dump, how long does it take?
Once submitted, the turnaround can be pretty fast, between 12 to 48 hours.
When you submit a dump, ensure that:
- You are using the latest version of MakeMKV
- You are using a LibreDrive-enabled drive (be it 'friendly' or 'official', but it must be LibreDrive enabled)
- You have 'Enable Internet access' enabled in Preferences (in the General tab)
- You are opening the original disc (not a backup, not ISO, etc)
- You are opening the disc using a real disc drive natively (no elby clonedrive, no vmware, no dvdfab or discsoft virtual, etc)
I see a movie discussed in the forum, but MakeMKV won't open my disc.
There are multiple versions of UHDs for each movie (countries, retailers, rentals) and there may be multiple keys for even the same version, so it's possible that your particular disc isn't decrypted yet. Submit the dump file!
Is there a way to 'test' a disc to make sure the disc is good?
If you're waiting after submitting a dump, you can use MakeMKV's Backup function to copy the entire undecrypted disc to your hard drive in order to test that the UHD itself is good, and then once the key is available, you can use MakeMKV to open the disc backup off your hard drive. When you start MakeMKV, don't open the disc - just push the Backup button, an icon with a green arrow pointing into a yellow folder, second-from-left in the top row of icons.
Playlists
I see multiple titles for the main movie, which one do I choose?
Just as with Blu-ray discs, there may be multiple titles on the disc for varying reasons:
- If the disc has multiple cuts, such as theatrical vs extended.
- One may be the mpls playlist with chapters, the other the m2ts source file.
- Disney discs will have multiple titles where the difference is localization for the titles and credits. English will be 800, other languages will be 801, 802, etc. (Some older discs might be something like 200, 201, 202, etc.)
- Some discs have one playlist for English/French/Spanish/etc, and a second playlist for English/Japanese.
Problems
MakeMKV reports MEDIUM ERROR or 'corrupt or invalid at offset' errors while ripping.
This means that MakeMKV cannot physically read the medium (the UHD disc). This is usually due to either the disc not being perfectly clean (check your disc thoroughly from different angles under a bright light and carefully use a soft dry microfiber cloth to clean it) or it could be due to a defective disc, which can happen with all disc-based formats.

When I watch a UHD rip, how come I see blockiness, or the audio stutters, or the framerate won't keep up?
Some recommended playback software has been http://mpv.io or http://mpc-hc.org with madvr. Also, check out our UHD Processing thread for discussions on reducing bitrate with software such as Handbrake. VLC generally has not been up the task yet, and isn't recommended.
How come my powerful computer (insert specs here) can't play MKV files smoothly?
A bit of technical explanation: On Blu-ray, each h.264 frame is encoded as 4 independent slices - this means that it is possible to decode any given frame using 4 parallel tasks. On UHD, each HEVC frame is encoded as 8 independent slices. Hardware decoders take advantage of this, but open-source software decoders don't use such acceleration. That's why a smart TV can easily play a high-bitrate HEVC from UHD, but could fail even on much lower bitrate MKVs from Handbrake. (Thanks to Mike for the info!)
When I watch a UHD rip on my computer or on a non-HDR TV, why are the colors muted or flat?
HDR UHDs contain metadata for the HDR. They also use Rec. 2020 / BT.2020, which is a 10-bit or 12-bit WCG (Wide Color Gamut) color space (compared to Blu-rays or SDR UHDs, which use the Rec. 709 HDTV color space). If you view HDR content on a non-HDR monitor, the colors will appear muted. Some playback software, such as http://mpv.io or http://mpc-hc.org / mpc-be with madvr, have various 'tone mapping' methods to display the video - usually adequately - on non-HDR monitors.
