I have a Vizio E55-C1 smart tv and it is working well with Mezzmo V 4.1.3.22. I have a bunch of videos, mostly WMV with a few MPG, MP4 and MOV.
The profile for this TV only mentions MPEG for video (along with various photo and audio formats).

Does that mean Mezzmo is transcoding everything to MPEG? I'm not well versed in reading the profiles, obviously!

The Vizio documentation does not mention which formats it supports - gee, that's helpful!

Can I determine what forms are supported by turning off transcoding and then trying to stream some videos of various formats?
