I have the same problem described, It was difficult for me to understand the solution because I am a beginner
in the Multimedia community , but after the search I have passed this problem, of course this thread was the key to the solution and that’s why I want to put the solution Step by Step to those who are like me —> Beginners.
Description of the problem:
When the WDTV Live try to open MKV file it hang and can’t play anymore no one files.
(If you have played the video before using the WD TV Live but you can’t play it now then I guess you have to try Step 1 Only , Otherwise I think you have a different problem)
Solution:
Step 1 :
As suggested in the main post :
“When the WDTV Live try to open one of those files, it hang, and can’t play anymore no one files, even if it is power off. The solution to restart the playing function is to press 1 second the reset button when the WDTV is on.”
But for me it was enough to turn off the power (using the remote) then removing the power plug and insert it again.
Step 2:
Download “mkvtoolnix-unicode-4.3.0-setup.exe” file and install it.
I have download it from “free-codecs.com” see the link: http://www.free-codecs.com/download/MKVtoolnix.htm
this version have fixed the bug, I have tried it and its worked fine with me.
Step 3:
Launch the “mkvmerge GUI” (This shortcut should appear after installation, it will ask you during installation if you want to place a shortcut make sure to check it, otherwise go to you programes list and run it)
Step 4:
Click “Add” and choose the movie that have the problem (The MKV file) then press “open”.
You will see at the bottom that the “Output filename” is containing an additional “(1)” you can change it to any name you want.
Then under “Tracks, chapters and tags” you see a list of your videos/sounds/text that are attached to the movie you have just added.
Click on the first one then go to “Extra options” tab and click it, from the “Compression” list choose “none” that’s it.
Do the same for every line in the “Tracks, chapters and tags” list.
Step 5:
Click “Start muxing” button. and wait until finish.
I hope this help
