I have Mezzmo Pro 5.2.0.0 running on windows server 2016 essentials.
I can stream to many devices (PCs,Fire TV, Roku ETC) all of which can see all the files on the server.
I have a Toshiba smart TV with DLNA client that plays and displays most of the files, but some are not presented in the list.
E.G. I have all episodes of Breaking Bad saved as MP4 files but series 1 episodes 2,3 and 6 do not show, but all others do.
All other devices do show these...

Any Ideas ?
