It was set to LG TV manually by myself after Mezzmo auto detected my tv as an LG Bluray Player (LPCM).

Also I chirped in on this post as since the update mezzmo (which worked fine) has now ceased working and is showing the same problems as what Hazy describes where video files that displayed fine and played on older version are now not working and it appears mezzmo is searching for image files instead of just accepting the video file and playing it like it usually would.

Have submitted ticket in regards to my issue as very frustrated, this needs to be fixed with new update ASAP.
