How do you store videos into your MP4 Player?

Hello.
I have a MP4 player bought straight from China. It was made by the "Beijing Xingyuehuacai Digital Technology Co. Ltd company and it's name is "MP4 GM600". I'm just wondering how do you store video files into your MP4 player using USB? I've converted my video files' type to .amv, created a folder named "MP4" in my MP4 player (using USB) and added the video (.amv type) into the MP4 folder I created but it still doesn't work. It says there (in my MP4 player) "No files". I tried adding my audio files into a folder named mp3 (in my MP4 player using USB) and it worked. Can someone help me please? I've wasted a week just to find out how to store the video files into my MP4 player

Try it withOUT putting it in the "MP4" folder. Just put it in the main root of your player and see if that works.
