Trouble playing video on vizio tv

I have a wd live duo containing music, pictures, and video. PC is running serviio. I have a Vizio tv.
On the serviio console, I see the vizio tv and set the profile of the ip address to vizio tv.
From the Vizio tv, I can see the Serviio dlna.
I can see and play the movies on the vizio tv::serviio dlna.
On the vizio tv::serviio dlna, I can see the movies but I cannot play any of the movies. For some reason, there is a .mpg appended to every movie (flight.avi.mpg, flight.mkv.mpg, etc.). Also, I can't see my pictures but this is less important. I'd really like to be able to play my movies from the serviio dlna on the vizio tv.
I also have a wdlivetv. For kicks, I setup serviio profile for the wdlivetv. From wdlivetv::serviio dlna, I can play movies fine.
Any ideas why my vizio can't play movies? How do I remove the extra .mpg suffix? The files on the server don't have it. They just have flight.avi
