LG 3D TV HELP!! not support audio for .mkv videos

I tried playing a .mkv video on my LG 3D tv through the usb, but an error came up saying "unsupported audio." The video comes out great, but the sound does not come out at all. Also the subtitle does not come out when played on the TV, but comes out when played on the PC.

I tried the converting with audio from DTS to mp3/mpeg but the quality of the video dropped immensely even though I chose not to change to mkv format. I used the freemake video converter program.

Is there a way to convert just the audio and not the video quality? I've updated the TV with the latest firmware also but no luck.

This video is from what DVD and why not start with your source media rather than lose the quality?

Also, this same story has been repeated far too many times. That is, a HDTV is not a PC. The encoding support is limited.

Well I could play this in a blueray player or even hook my hdmi from the computer to play. However my goal is to not only play the movie in the SBS 3D format, but also be able to show the subtitles as well.

I forgot to add a software title.

In reply to: Okay

Look up AVIDEMUX. Sorry I can't write a tutorial in my replies but there are such on the internet.

-> You write the other files work fine. That's good. Now create your new files using the same encoding and methods. In simple terms "Use what works."

Use freemake audio converter to convert the audio to AAC.
Then drag and drop the orginal mkv and the new aac into mkmergeGUI, uncheck the original DTS audio and make a new mkv.

Your method actually worked! thank you so much!

I was also wondering how to have subtitles be read with its mkv videos on the LG 3D TV. Videos in avi or any other common videos formats with their respective subtitle files (subtitle file with the same name as the video) seem to all work on the TV except for the mkv videos ( and its respective subtitle file). The subtitles files for avi and etc are in (.smi) but the subtitles that are for the mkv end with (.sub).

I apologize if my writing is confusing and hope that this situation can be solved like my previous one Grin

LG TV Subtitles

In reply to: THank YOU!

According to the manual
Supported subtitle format(external) :*.smi, *.srt, *.sub(MicroDVD, SubView1.0/2.0), *.***, *ssa, *.txt(TMPlayer),*.psb(PowerDivX)y

Supported subtitle format(internal) :XSUB(Only, XSUB is the subtitle for-mat used in DivX files), Text UTF- 8,SRT,***,SSA(Only, this is the subtitleformat used in DivX-Plus HD files)

Personally I just try to stick with .SRT format subtitles because my PVR and my LG TV can use them and they are just text files which can be edited. For mkv files these can be external files with the same name as the video but with a .SRT extension or they can be inside the MKV file.

If you can't get your .SUB to work and it can't be converted, just try searching for a .SRT version.

please explain what did you mean by uncheck the original DTS

Yes, there is a way to do it

In reply to: LG 3D TV HELP!! not support audio for .mkv videos

I described how to convert unsupported audio from videos in my blog. Also, I included download links to free apps.

Basically, you need to convert the audio to AAC and then merge it to the original video. So, the video is not modified and the conversion is fast.
