"AllShare drops the connection to Serviio server"
I thought AllShare was for Samsung things and devices. You seem to be trying to stretch what this app does.
Another Samsung 'fail' - AllShare drops the connection to Serviio server randomly. Makes it useless as a player.
Same Serviio setup and media files play perfectly via XBMC on a Raspberry Pi.
I really have severe doubts that Samsung developers actually know what they are doing.
Reporting an error to Samsung service by their convoluted mail system is a total waste of time as the agents while polite are clueless in offering any practical help.
