Hello i find mezzmo the best dlna server for me. Im using trial version and I want to buy but.

I have problem with flac files. My bluray player (PIoneer BDP180 easily read almost all FLAC files on USB, and other server) but on mezzmo i cant see files in catalouge.
What i discover i get this when using Pioneer BDP profile. I changed to Pioneer VSX profile and i started to see my flac music, but there was a problem when i open mkv movie the subtitles didint work. I tried all pioneer profile, but i had problem with subtitles / flac files. I would like to have all supported files on one profile. Can u do something with it and i can then buy your product?

Sorry for my english Im not native
