Have used mezzmo for years and love it but with the latest updates it seems that for most mkv files I get the video codec not supported error. All of my mkv files used to play just fine, now only the odd few will play.

I have updated the library and the playlists, etc. but still the same issue. All the files show in that they can be selected but most of them spew out that error.

How can I fix this?

Thanks.
