Haven't seen this codec before

I am still encountering an occasional issue with some of my UHD movie rips. I'm trying to play it on my Roku TV. This one in particular I didn't notice before. While the UHD case calls it Dolby TrueHD with Atmos, MediaInfo is reporting it a little differently.
  Code:
Audio #1
ID                                       : 2
ID in the original source medium         : 4352 (0x1100)
Format                                   : MLP FBA 16-ch
Format/Info                              : Meridian Lossless Packing FBA with 16-channel presentation
Commercial name                          : Dolby TrueHD with Dolby Atmos
Codec ID                                 : A_TRUEHD
Duration                                 : 2 h 7 min
Bit rate mode                            : Variable
Bit rate                                 : 4 991 kb/s
Maximum bit rate                         : 7 662 kb/s
Channel(s)                               : 8 channels
Channel layout                           : L R C LFE Ls Rs Lb Rb
Sampling rate                            : 48.0 kHz
Frame rate                               : 1 200.000 FPS (40 SPF)
Bit depth                                : 24 bits
Compression mode                         : Lossless
Stream size                              : 4.44 GiB (9%)
Title                                    : Surround 7.1
Language                                 : English
Default                                  : Yes
Forced                                   : No
Original source medium                   : Blu-ray
Number of dynamic objects                : 11
Bed channel count                        : 1 channel
Bed channel configuration                : LFE


Is Meridian Lossless Packing something we can capture with a profile? I don't see it listed as a Matches codec. Or is this just the way that TrueHD is identifed?

My Roku TV is playing it without transcoding, but several minutes into the video it stops and reports the file as unplayable. I've encountered this before with DTS Master Audio: playback starts but then stops with the same error. For DTS/MA, I just transcode to DD and it plays fine. But the console is reporting this as no transcoding. Since no Roku supports any lossless audio codec, I am very puzzled why this even plays at all, regardless of the error message.

I also discovered an error in the Roku 4K TV profile, where it is transcoding video when I meant to only transcode the audio. I will submit an update for the next version.

Re: Haven't seen this codec before

Looks like it's something that MediaInfo is interpreting differently (or just embellishing) then FFMPEG. Here's the FFMPEG info.

  Code:
 Stream #0:1(eng): Audio: truehd, 48000 Hz, 7.1, s32 (24 bit) (default)
    Metadata:
      title           : Surround 7.1
      BPS-eng         : 4991233
      DURATION-eng    : 02:07:21.635000000
      NUMBER_OF_FRAMES-eng: 9169962
      NUMBER_OF_BYTES-eng: 4767647940
      SOURCE_ID-eng   : 001100
      _STATISTICS_WRITING_APP-eng: MakeMKV v1.12.2 win(x64-release)
      _STATISTICS_WRITING_DATE_UTC-eng: 2018-05-28 03:07:59
