Is there something on the TV I need to ensure is configured properly?
Possibly…
But first, you should check the user manual of whatever TV you have, and see if there is a list of media formats it supports via DLNA, and check to see if it supports the media file type you are trying to play.
Also use the Twonky UI to see if there is a ‘Media Receiver Type’ that matches your TV. See the Twonky FAQ for information on that.
