Been using this for a couple of months to remedy a problem with some TV MKV WEB-DL and movies both, which will not play on either of my stand alone BR players. Simple and very quick conversion and every file has the same quality as the MKV and plays perfectly in my BR players. I would highly recommend this software. It has also made the files smaller as it changes the audio.

Converted an MKV with DTS as audio, default settings, have Quicktime, when uploading to YouTube:

Alert icon
The video you uploaded may have audio/video sync issues. Please refer to this article for advice on how to correct this issue should it arise.

Final product on YouTube was adequate but the speech seemed out of sync by a few milliseconds (hardly noticeable).

Cool software, thanks!

we recently bought sony ex520 and i converted MKV files to mp4(to size less than 4gb) but they always stop playing half way when used fwd with an error message "playback ot available". I tested various encoders like handbreak, xvid4psp,freemake etc. but no use. finally i tried mkv2mp4 to change the container and then reencoded using freemake to reduce the size below 4gb. (mkv file is a Blueray disk rip to 4.35gb, play time 2hrs.45min). excellent result and worth trying. just one thing it lacking is encoding function to resize the mp4 file.

First, it crashed on my system, too. After downloading the source and running a debug it was obvious the MediaInfo.dll in the "mkv/avi to mp4" package that caused the problem. I didn't want to change the code and tried to substitute the MediaInfo.dll.
Fixed the problem replacing the delivered MediaInfo.dll (0.7.33) with the newest version (0.7.39). And it worked!
Great program, thanks!
