MKV doesn't play but MP4 with same audio+video streams does, using Network Share

Hi everyone,

I’m new to the community, so, HI everyone! It’s my first post here so if the topic was discussed, please go easy :wink:

I have a WD TV Play and after spending several hours online, I’ve managed to share content from my Windows 7 to my WDTV Play through the local network. If there’s interest, I can share a small guide on what needs to be done (I had permission issues and I managed to get everything fixed with ICACLS :wink:). My setup is: Windows 7 and WDTV Play, both in the same local network and connected to a router. I used Windows Media Player libraries for sharing and the “Sharing Folder” option in Explorer.

Now, once I got everything I wanted shared and visible in WDTV Play, I noticed that most of the file formats play fine but none of the MKV files do. WDTV Play sees them, including thumbnail - but doesn’t play, complains "Unable to play the selected file. Please see the User Manual for a list of supported file formats)

However, when I process a MKV in XVID4PSP, using stream copy for both video and audio and selecting MP4 as container, the resulted MP4 file plays perfectly on my WDTV Play. So basically, the streams (audio+video) are good, but WDTV Play doesn’t like the MKV container. It does like the MP4 one.

[LE] I have also checked and the MKV plays fine in the WD Play external USB. I can’t find any info in the manual saying MKV playback in the network would be a problem?

Can anyone give me some quick tips on how can I quickly fix the MKV files without converting them all to MP4?

Here is MediaInfo (0.7.65) example of a MKV file that doesn’t play but was “converted” to MP4 and plays fine:

Hi, see if the following link helps.

Thank you, Ichigo. Indeed, I’m still not sure if the problem is that I’m using Windows as media server. As I later edited in my first post, WD Play does see and play correctly the files when connected through the USB but not from the network.

To add to this, it seems that the subtitles also don’t show when playing from the network. They show up when playing from USB, which may indicate a media server issue. If this is the case, can someone recommend a free media server that works in my scenario? I don’t have a PS3 and I’d prefer to keep things simple (software).
