Problem with video files

I have a problem with video files, i dont know how to copy them to my sansa player i used many converters and try many things and it doesnt work. I didn`t see any video file or sansa player “say” me that i must convert this file.

Could someone tell me step by step how to copy video file to sansa fuze player ?
