Ok, I have hundreds of MKVs. Usually they are quite large, if you have many MKVs in one folder, of course it will choke populating it.
MKV files are automatically associated with the Movies and TV tile app. But the Tile app CANNOT play back the Audio portion of an MKV. So what you can do is install VLC and associate MKVs with that immediately, and this should stop. It's because they are assigned to the wrong handler, that's wy the folders hang.
The other issue is that all Video files will insist on showing a Poster Frame if you set Large Tile view.
So, set the folders that have MKV's to Detail or List view, then they should not choke populating. Hope this helps. Mainly it's understanding your content and codecs, no other player but VLC for Desktop can play ALL codecs, and once you assign it to all file types, your problems will vanish.
