Extract the audio using mkvextractgui.
Convert the dts to ac3 using eac3togui.
Add the new ac3 to the mkv using mkvmerge.

You can also try PopCorn MKV AudioConverter. I have the same problem with DTS audio and found this worked for me.

I use XVID4PSP to do DTS to AC-3 when I have a MKV with DTS audio. You simply set it to AUDIO only mode then load the MKV and I set it to 640 AC-3 and it will spit out just an AC-3 audio file.

I do this because afterwards I use tsMuxeR to create a M2TS file which has the video from the MKV with my new 640 AC-3 audio track. Thus I can play the file on my PS3.

You can also use 448 AC-3 if you prefer (that is what DVD uses for 5.1 audio but devices like the PS3 can handle the higher 640 bitrate).

Add the new ac3 to the mkv using mkvmerge.

Same starting point for me. I need to change DTS to AC3 and I already used mkvextract and megui to create an AC3-file of the DTS one. But when I wanna use mkvmerge to include the ac3 file to the mkv-container I get ERROR-Code 2 with the message

"Error: The source file '--ui-language' could not be opened successfully, or retrieving its size by seeking to the end did not work."

Always exactly this one, independently what file I deal with, even if I don't change anything within the container.

Firstly I thought its a mistake with the language-file of mkv-merge, but neither changing to another mkv-merge-version (2.9.8 to 2.9.7) nor changing the language of the GUI is working...

@aaron1104 - If you're going to have to do this all the time, maybe it would be better to just bite the bullet and buy something that supports DTS audio like the Western Digital media players. Here's a recent thread on the new version they just released:

No need to convert DTS audio when you use this player.

Dear all,
I'm not usually using forums but this time after too long time consumed to understand the problem I finally solve it.
To convert the DTS to AC3 you can simply use the following 2 applications:
> MKVToolnix (http://www.softpedia.com/get/Multime...VToolnix.shtml)
> WAV to MP3 (http://wavtomp3converter.com)...for this last you can find a lot of freeware alternatives

The steps:
1) use MKVmergeGUI application (included the MKVToolnix package) to open the MKV video file.
2) check in the Input tab (Tracks, chapters and tags), the DTS file(s) only! (rest must be left unchecked)
3) Press "Start muxing" and so you will create MKA audio file(s) out of the MKV
4) use WAV to PM3 application (or other) to convert the MKA to AC3
5) open MKVmergeGUI again, Drag and drop (or by "ADD" button) the original MKV file and the newly AC3 as well.
6) Check only the boxes related to the video file and the AC3 file (and any file you consider to have in addition but except the DTS file which should no more be included).
7) Start muxing this last set of files and the result is the MKV file with the AC3 audio.

This is quite easy method and you should have no problem by following these steps.
Hope I could help!

Anyone have a way to convert DTS to Dolby 5.1 on Mac OS X? I can export an mka using mkvtoolnix and I can even load it in audacity but audacity cuts it short to like 45 minutes which is not useful if you have a 2.5 hour movie :O If only Compressor supported Mkv!

Try ffmpeg or ffmpegx

Is there an all-in-one package that's simple to use (even a paid app will be fine). Want to be able to show my wife how to do it so it needs to be a sensible gui and not several different apps to arrive at the outcome required. Surely there must be an app somewhere that lets you input an MKV file with DTS and let you output an MKV file with AC3 (or whatever).

Cheers

Hi, I also just ran into a problem with this. First happend to me when trying to convert DTS to AC3 for AVATAR, never had to do this before (remux) so I searched yahoo and eventually came across a post here (this site is really informitive, love it) anyways... from that post, I saw some suggestions and decided to use popcorn. I downloaded it, got it all setup and it worked perfectly fine for 2 MKV's now I tried it with a third one and it didn't work. I got an "error 1" (from popcorn) I can't remember all the exact info but something about libav. The thing is I also got a similar/same message for the second MKV and it still worked fine, But for this one, it didn't???? Can anyone help me out? Attached MKV info as text (didn't wanna have this huge post that is like a whole page long... can't stand when people do that)

Edit: I tried doing the steps manually. I used mkvextract gui, extracted the DTS file, then tried using eac3to (EAC3toGUI_v2.00) and this is the message I got:


Anyone Know a different decoder that will work?

I have a problem with MKV2AC3 version 1.03.03. The audio in my movies stops playing during the last quarter of the film.....The source file works perfectly. anyone can suggest something?

[Moontrash]

Use MKVcleaver or MKVtoolnix to demux the audio

load the DTS track in XVID4PSP and choose what settings you want it at

remux the track with mkvtoolnix

done

super simple

thank you it worked on the first movie i tried......So you recon that MKV2AC3 has a time limit for encoding?

Just converted Robin Hood blu-ray (Russell Crowe) soundtrack - DTS to AC3 using MKV2AC3 (x64 ver 133)
Admittedly I played around with MKV2AC3 and made both it and eac3to portable and combined the two in a single package. [Purely for my own convenience]

Point is, that movie is 2hr 35mins 50sec long and it converted the DTS just fine. No hiccups whatsoever.

I remuxed the AC3 audio with the MKV. Again, no problems or sync error.

I did nothing to the programs themselves, so I have to assume the x64 version works just fine.
Can't vouch for 32 bit version.
