I have a samsung smart tv and a denon avr-e300 home theater receiver that both are DLNA ready. I have emby server installed on a FREENAS server with a static IP. The Server, TV and receiver are all networked and have Static IPs. Emby works beautifully on all my devices using the webserver IP except on the DLNA devices. It says the video files are music files, then error out when I try to play them. I have tried .mkv and .mp4. What other file
type should I use?
