Play movies from usb on NAXA TV ntd-2457-A

Did you download in tablet or computer? Are those movies olayable on computer? If they play on computer it would mean that your tv cannot handle certain codecs or formats and you need to re-convert those movies to format understandable by tv. If they dont play on computer then either file is corrupted or you downloaded "fake" movie

Nope, you certainly can't. The TV can only show still photos or play music. It's not capable of playing videos.

Burn your movies to DVD or Blu-Ray and you can plug a player into the TV, also described in the manual.

Some TV models have a USB port so that users could play videos and movies from USB on TV. You can try the following steps:

1. Connect your readable and writable USB drive to computer
2. Copy your movies to USB drive and then disconnect your USB drive from computer.
3. Connect the USB device to the Sony TV USB port. Turn on the connected USB device if necessary.
4. Press the HOME button on Sony remote controller to open the menu.
5. Enter the target USD drive.
6. Select the file you want to play back, and then press the play button to start playing movies on TV via USB drive.
It's quite easy to play movies from USB on smart TV devices.

maybe you did not properly select the right application in your tv... example if you play movies go to movies menu and if thats music go to music menu and also for pictures go to picture menu......or the format of you data is not supported of you TV..

i have a 32inch hisense led tv i watch movie using usb but it stop and back to the begining when the movie is over 2hours.. hope you can help me .

The TV can only play a specific format of video. You may be using MP4 files while the TV can only view 3GP or FLV formats; just try downloading a converter (I've used FLV Converter on Windows XP for years, works fine and very simple) and changing the file format.

The file format maybe wrong check the device your using to play movies with and see what type of files it plays etc.

from usb these players will play only certain type of formats,,,
store movies in some other format and try... it will work.

I would advise knocking down the resolution. Try and use software, like red kawa, to convert a few of your movies to different formats till you find a decent one. A widely accepted codec setup is Divx/XVid (both are the same) and MP3 sound.
