For the last 3 days I have tried to encode or render video files to use on my new tv.

Every file I highlight in the TV menu shows Format not supported, and when I try to selected it at the bottom of the TV screen it gives me a message that reads.

Format not supported
Supported format: motion jpeg, 320 x 240, 30 fps

I have tried at least 20 different encoding of movies in the .AVI format (the included manual showed .AVI as the only supported video type.)
No matter what I do, I can't play a movie.

I have searched the sites, and have found little on my model of TV, if I have missed the answer, tell me where it is.

Any help would be appreciated.

Current Software/Firmware? on the TV shows to be TVNB013_00_PF_XX91_AA.

The mediainfo for the last video I tried to encode is
