Windows Media Player won't play MKV files in Windows 7

Post by DodgerBlue on Mon Jan 26, 2015 4:22 am

I have the latest Mega Pack 10.9.5 installed on a Windows 7 Ultimate 64 bit PC. I cannot for the life of me get Windows Media Player to play any of my MKV files. WMP does just fine with all my other file formats (M2TS, MP4, etc).  Also Media Player Classic will play MKV files with no problems.  When trying to play the MKV file in WMP the program will open up to the correct media resolution window size (ie 1280 x 720, 1920 x 1080 etc) but it will not start playing the file. You can move the slide control to advance the movie to a later point and it will display a still image of the movie but it will not actually advance further from the still.  In fact it will only display the still for few seconds and then the image will go much dimmer and a window will come up and say that the program has stopped working and give me the option to close it.  I need to be able to play MKV files on this PC in WMP as I am using it as a home theater pc and am using Windows Media Center.  I will include my log for KLite as well as media info for one of my MKV files:

As a side note I also have an identical setup on another computer (same OS and Klite pack) but have absolutely NO PROBLEM at all playing the exact same MKV files in WMP. I'm confounded as to why I am having this problem.  Please help!!!  Thank you in advance for your generous support! Laughing

Re: Windows Media Player won't play MKV files in Windows 7

Test if playback works in the GraphStudioNext application (the x86 version, since default WMP is also 32-bit). It should use LAV video decoder or ffdshow.

Two things you should check:
Codec Tweak Tool > Win7DSFilterTweaker > Preferred decoders > H.264 > should be set to "Use Merit" by default.
Codec Tweak Tool > Win7DSFilterTweaker > Media Foundation > There should be no entry for .mkv. If there is, then disable it. That is a left-over from DivX software bundle.

Thank you for the quick response! I tested playback in GraphStudioNext 23 bit and it plays just fine (FFDSHOW).
I also made sure the settings on Win7DSFilterTweaker are as you recommended.
It still cannot get the MKV file to play in WMP however.
What do you think the problem may be?

The settings are correct and your system is very clean. That video file also looks just ordinary.

One last thing you could try:
Codec Tweak Tool > MS Codec Tweaks > Disable the Microsoft DTV-DVD audio and video decoders

Re-enable them if it does not make any difference.
