How can I go about installing Dolby Reference Player (DRP) ?Music Media Helper 6.3.13 Released:
Version 6.3.13 (January 18 2023)
-------------
New:
Atmos Helper: Added Atmos Decoding (beta version) to MCH WAV option - Only if user has a Dolby Reference Player (DRP) installed
About the Atmos Decoder tool beta:
This tool not formally documented yet. I'll do that ASAP. This is an experimental beta release.
The new Atmos Helper Atmos Decoding tool is a beta and is currently undocumented. It only appears as an option on the MMH Atmos Helper main dialog if a user has the Dolby Reference Player (DRP) installed on same PC as MMH.

This uses the DRP to decode a file with an Atmos stream contained in any of supported files to either multiple mono wavs or a single multichannel interleaved wav. Users can add multiple files from a single folder (it will batch decode):
Supported Input Files (With Atmos - TrueHD or Dolby Digital Plus JOC):
MLP
EAC3
MKV
MKA
MP4
M4A
For each of the above the tool extracts mlp or eac3 then decodes to the selected output wav type (Interleaved MCH or mono).
This tool will probably fail where a user has split any mkv into chapter files as the DRP is not compatible with splitting MLP streams. In this case users should decode from the original MKV rip containing all the chapters (songs).
For MKV and MKA files containing chapters the tool first Decodes the entire MKV/MKA file (takes quite a while). Then it splits the huge wav (.w64 file) into chapter files. Be patient.
The Atmos Decoder supports the following WAV output (Channel Layouts):
Stereo
5.1
7.1
5.1.4
7.1.4
9.1.6
The DRP remixes the Atmos stream to selected output channel layout, just like an Atmos AVR remixes to the user's AVR speaker layout. Nothing is lost.
The decoder creates a relatively quiet pcm wav. There is a user option to apply a volume gain to all channels. Please experiment. Of course, MMH's Channel Volume tool can also be used to apply channel gains to specific channels (i.e. boost rears or tops only)
Interleaved MCH wav files have correct channel mask (channel IDs) for wav players that support this and are compatible with the Atmos Helper‘s Atmos Encoder tool (allowing, for example, channel volume edits and re-encode to back to Atmos). Mono files are named in Dolby channel order and with channel name suffix.
Please post questions/feedback here.

i use latest version of MMH and also found same error like u mate, already found the solution?I use MMH version 7.2.10.
Dolby Reference Player version 3.2.0
It's just a remuxed english atmos from web.
See screens in attach.
always works when output channel 5.1.2 but if set to 5.1.4 / 7.1.2 / 7.1.4 which channel presentation should set to 16, some file work, some not, i thought it was because the size, but after i trimmed below 1 gb, it still got an errorTry changing the ‘TrueHD Channel Presentation’ to 8
Indeed... It's not possible to tag mlp (Packed PCM (PPCM)) files. And even if you extracted the LPCM stream and muxed it within the .wav container very few playback devices can read their meta-data tags either.I don’t know of any way to tag mlp files. Many AVRs won’t recognise files on USB drives, especially Atmos/TrueHD.
