how to fix your mkv

[tachita]

sience mkvtoolnix v4.2.0 bring a header compression that is not supported on realtek players and until this will be fixed, i dare to post a link found on asus oplay forum that will fix mkv's automaticaly for non-tehnical minds.

or you could use the mkvtoolnix interface where you can choose non compression.
both variants work fine:

So in the last few days there have been a few posts from people getting "invalid file" when trying to play some mkv's. This is likely due to header compression that became a default feature in the lastest editions of mkvmerge (software used to create the mkv's).

I was using mkvmerge to remux the files without compression. I was recently "googling" and found a "simple" way to fix them. I found this on some forum (unfortunately I don't remember which one or whom to credit for creating this file).

1) First you need to install mkvtoolnix on your computer:

http://www.bunkus.org/videotools/mkvtoolnix/win32/mkvtoolnix-unicode-4.2.0-setup.exe

2) Create a folder in a location of your choice...say "My Documents" for eg. Name it something like MKV Fixer.

3) Download this zip file and extract the file "FixMkv_toolnix_installed.cmd" to the folder you just created.

Alternate:

4) Now when you get a .mkv that shows up invalid, simply place it in the Mkv Fixer folder, click on the FixMkv_toolnix_install.cmd file, and a command prompt window should open showing progress and it should repair the file,and it should then play on the Oplay.

I've tested it on a few "invalid files" and it has worked perfectly!

and the cmd line, for you to not have to wait that much:

Also thanks, great tool 
Because of this tool I finally can watch my (only audio) movie on the mede8er.

Tip: Instead of copying the mkv file to the "mkv fixer" folder, copy the "FixMKV_toolnix_installed.CMD" file to the movie folder!
Is much faster!

or you can drag your mkv over mkvmerge app and choose no compression

...or merging with mkvtoolnix 4.1.1

   * Released v4.3.0.

   * mkvmerge: bug fix: Appending tracks which would normally be
   compressed (e.g. with header removal compression) and turning off
   compression for those tracks with "--compression TID:none" (or the
   corresponsing option in mmg) was resulting in the second and all
   following appended tracks to be compressed all the same.

Is that mean that the problem is solved with that new version ?

i installed version 4.2... of mkvtoolnix. I then copied the code aboved into notebook, removed the three lines that state 'REM' and saved it as a *.cmd..., placed the file into the mkvtoolnix folder. placed my 'corrupt mkv' (badmkv) into the folder aswell and ran the cmd file. A dos box appeared for like 1 second. i did not see any changes happen to the badmkv. it still does not work, however if i run the program mkvtoolnix (mmk.exe i think it's called) and add the badmkv and go through all the settings and 'remux' it, it works... my question is why does my .cmd file not work? even dragging the badmkv onto the .exe as stated above, i get a 1 second dos window...but anyways at least i can get it working even if i must do it the long way. thanks for the help guys. i just revived some awesome episodes i had missed.     windows xp with sp2.

Try to right click on the cmd.exe file and somewhere is an option where you can choose it should stay open. atleast it was so in windows 2000. In windows 7 there is no option whatsoever.

Another way would be to open the cmd.exe and simply go to the folder where the files is (it would be helpful if it would be an easy to reach folder) Example if it is on C:\movies\ . Normally the DOS box starts in you folder eg c:\users\admin\ . Simply type "cd\" and then "cd movies". Now you need to type in simply the name of the cmd file.
