Your model does not support video playback through usb, you could however try the link below, good luck !!

Could be an unsupported video format, have you tried downloading the movies in mkv, avi etc etc. Other than that i don't see what could be the problem.

Check the manual for supported video formats.

Is the video format check the format your TV supports

May not be fast enough copy the files to you computer then try.
