Hi!

I have an issue with some of my .MKV files that i try to sort out.

Some of them will not play using Mezzmo.
First of all, I have turned transcoding off, since i really want them to be played in naitive mode and dont stress out my pc unneccecaty.

I have tried using USB playback, and then do the file play without any problems.

Soo the basics of it.

Why do this file NOT work using mezzmo with trancoding off?

Is it the videobitrate? or the h264 encoding (High vs Main)?
According to the TV's documentation it should support both, and like i said, it works using USB playbak.

As you might understand by the filenames i have started to play around reencoding the files using other encode settings, but it would be nice to know exactly why the file wont play so i know what files i need to fix, and do not encounter the problem when the popcorns are all popped and my girfriend is all tuned up :)

Any suggestions???

I have finally managed to work this out.

The mkv file that won't play through Mezzmo said 'media file not supported' and I thought it was due to the video codec.
But it was the 5.1 sound codec that was the reason, I reencoded the file, not touching the video stream, but recoded the audio to 2.1 and then it worked!
Another thing I also found out was that older firmware on the TV wont play mkv files through DLNA at all. so id anyone has this problem, perhaps a firmware update of the tv is in order.

Glad you sorted it out :)

My other suggestion would be to try and re-encode as 5.1, but reduce the audio bitrate from 640kb/s to 448kb/s and see if that works.

I did some more testing, I could not play any 5.1 files no matter the bitrate. I went as low as to 48kb/s
I will do some more testing and let you know the result.

I can play MKVs with DTS or DD 5.1 no problem (Samsung UE32C6700).

Yes, the B models won't support DTS or 5.1.
5.1 works when using USB, earlier firmwares for B models won't support MKV's when streaming at all.
