mkv can't be loaded

[Maxim.Sakhankov]

Hello Hobedtor,
Most likely, the MKV files you talk about contain VP9 video. We added a support of such files in Video Splitter v.7.3.1906.10. Please check it and if id does not help, please send a sample of your file to our tech support or to me directly with the reference to this post.

Sometimes I would like to trim mkv videos. (from youtube) But I get always the message "some files are corrupted or not supported"
I thought mkv files are supported...?? Version
