Hey all,
I've recently been trying to play a few .MKV files and getting odd results. Trying to play them from a USB stick or external HDD crashes Media Player every time with no error message. The file attempts to play and the controls/info banner appears at the bottom of the screen, then the screen cuts to black and I have to hit the Home button to get back to where I was.
Initially I figured they simply weren't supported, then strangely, the exact same files played perfectly when I streamed them to the TV via Plex or XBMC, but not Sony's Homestream software. Neither of the servers are transcoding the files (XBMC couldn't if it wanted to), so they should only be able to play because they're supported by the TV. If this is the case, why do they crash via every other method?
I'm thinking this is the kind of error that's only fixed by a software update, but it can't hurt to ask.
Solved! Go to Solution.
The TV Engineers have responsed with an answer. They say that the issue is with individual MKV files with certain conditions when it has been encoded. Unfortunately the exact problem is rather cryptic and I cannot post it.
However they have suggested the following solution/work-around:
Using a program called MKVToolNix : HERE - remux the specific MKV files.
Ive not used this program before, so....
My next question to them was : Will they issue a FW update to prevent certain 'error' files from totally crashing the TV - I await the answer.

Hi
As others have pointed out this is more likely a problem with the way the mkv's were encoded or put together, i remux all my mkv's for compatibility purposes, and there are alot of badly encoded/created mkv's out there Ive found that certain languages of subtitles can cause problems with the .mkv container and also something called header stripping can also cause them to not play.
There is nothing actually wrong with the video and audio, its more likely the way that the container around the video and audio has been created, so as pointed out earlier using mkvtoolnix to remux the mkv can solve alot of problems, failing that then handbrake will fix it!
.mkv is like a box with the audio,video and subtitles contained inside
This is a great program that uses mkvtoolnix in the background to remux mkvs, it also adds a couple of compatibility fixes as they rebuild! it also allows you to remove foreign audio and subs which can save you ALOT of space
Hope this helps !
Hi there
Before jumping to assumptions here, I think we need more information on the file/s that are being played.
Can you please install a program called MediaInfo : HERE (its free). Open the video file through it, and post back all the details in text format. Don't worry, just edit any details that you think is not necessary (ie filename)
Cheers
Here you go!

Hi there
Thank you for posting the additional information. On the face of things, everything looks quite standard. However, looking more closer and comparing it to the supported codecs : HERE especially looking at the MKV container.
In the 4th column across from the left, is the supported audio codecs under the MKV container. There is no mention of MP3 or MPEG1L3. This 'might' be the cause. I stress MIGHT !
A suggestion. Use a program called Handbrake (also free) : HERE - convert the file, dont change the video format/codec, but re-encode the audio codec using AC3 instead (which is supported).
This would then either confirm what is causing the 'crashing' of the media player or at least ruling it out.
Hope this helps
Cheers
Hey,
I took a look at Handbrake but it doesn't appear to have a video passthrough option, so the video would end up being reencoded anyway. I've kinda given up on playing that particular file, PC will have to do.
Since I'm here, I've also had a few more problems since. The support for .MKV seems pretty bad, with some of them crashing Media Player and then completely freezing up my TV and remote. When this happens, not even putting the TV into standby is enough to bring it back and I'm forced to switch everything off at the socket.
Am I just coincidentally playing a string of unlucky files or is the support really this shaky?
Edit: It's worse than I thought, .MKV files that once worked now don't. When I first got the TV they'd say "content not supported" but play regardless, then after updating they played just fine... now nothing. I don't think I've updated anything at all since they were working, they've just stopped.
Hi there
Can you try a Factory Reset of the TV please - you never know.
Let me know if that works anyhow?
Also, another thread that you may be interested in is :

Hi there
Did you manage to do a Factory Reset by any chance? Are you also on the latest firmware? Just curious to know how you are getting on and is it still an issue?
Cheers
Hey,
I did a factory reset this morning. I'll try to walk you through what happened.
Hi there
Unfortunately I cannot resolve this problem and have no other suggestions at the moment. However I have reported this thread to Sony Support as an escalation in the hopes that they can resolve it (also in conjunction with another thread of very similar symptoms).
When I hear anything, Ill reply back in this thread.
Cheers
