Hello I'm new here and I've past the last hour to find a post that can answer my question but nothing precisely

I have a samsung BD-D5300 and I've Mezzmo installed on my pc, I got a connection through my network no problem at all, but I have a large collection of .mkv & .flac. I've incorporated them in Mezzmo (Video & Audio) I can see them on my TV, BUT there's the problem: if I go to All Video Files I can see them and if I want to play them I got a loading... and message : Not Supported File Format (and what is weird, it tell me it's .mpg ???) I got the same problem with the audio ... and if I browse direction in my added folders (where my files are) the folders are empty.

I hope someone can give me a clear answer because it's a great software that I'm going to bye if it works properly.

Thanks
