I am not home so instructed mother to make a debug.log
I remotely started PMS, asked mother to go into server via DLNA on TV. Wait few seconds and than I shutted down PMS.
Result is quite big log(80% of log are two blocks repeating continuously). To be sure problem is not some video detection algoritmus when mediainfo=true I shared one empty folder only(with one empty subfolder).
With mediainfo=false I can see shared folder together with "settings" folder(WEB.conf removed and medialibrary disabled for sure) but when true set, empty folder visible, also "settings" missing so it seems PMS sends folder info differently so TV ignores it?
Debug.log attached so who understand DLNA network communication, I will be much appreciated.
Later I will try to make wireshark capture...
