PN50C6400 - MKV won't play

[Sancus]

I'm using the Samsung C profile, and version 2.1.7 of Mezzmo.

Here's the ffmpeg info:

The TV reports "Not support video codec", but I have another file of the same video codec that plays fine, info following:

[matroska @ 0036cb40]Estimating duration from bitrate, this may be inaccurate

Seems stream 0 codec frame rate differs from container frame rate: 47.95 (48000/1001) -> 24.00 (24/1)
Input #0, matroska, from 'O:\Movies\avatars.mkv':
  Duration: 02:36:57.28, start: 0.000000, bitrate: 192 kb/s
    Stream #0.0(eng): Video: h264, yuv420p, 720x400 [PAR 1:1 DAR 9:5], 23.98 fps, 24 tbr, 1k tbn, 47.95 tbc
    Stream #0.1: Audio: ac3, 48000 Hz, stereo, s16, 192 kb/s
At least one output file must be specified

The only differences I can see are the audio, and the fact that the bitrate on the first movie reports as "N/A". As far as I can tell from my manual, this TV does indeed support DTS audio, and in any case, it's erroring on the video codec, not on the audio.

Is the "N/A" for bitrate significant? Is there something wrong with the way this .MKV has been encoded, maybe?

Yes, I can play a similar file here:

This is on a LA32C550 using "Samsung C" device profile.

One thing to check, is if you SamsungLA.prf (which is the "C" profile) MKV section is like the following:
