The best is if we can have the serial number to check the date of manufacturing... to be exact. But in general, the resolution of the video should be 720x576 or 720x480, AVI format. And you can put the video into the USB stick ( without any other files on it), wait for 30 seconds and the video should load on to the SD card. There has to be an SD card inside the player, for internal memory purpose. And it would remove the old contents and load the new videos.
Please e-mail to sales@glorystargroup.com if you have any more questions.
Cheers, Glory Star Sales Team.
