Trying to watch a MP4 video through the USB drive and the TV can find the folder that the movie file is in but not the movie file itself. The manual indicates that MP1, 2 & 4 are supported via USB. After trying a bunch of different things to no avail this is the response from the manufacturer:

Good Day!
I have ran into this in the past and our engineer said the
manual is incorrect. The TV can displays pictures and play audio, but
unfortunately it cannot play video via USB.

Anyone have any success playing a video file on this Television?
