Here’s a few links you should visit before you start posting:
http://www.xbox0.co.uk explains the scam
http://mympxplayer.org
http://www.s1mp3.org
http://en.wikipedia.org/wiki/Chinese_MP4/MTV_Player an overview of these kinds of players (with the emphasis that they have little to do with .mp4 files, but more with the chinese .amv .mtv etc. formats)
mympxplayer and s1mp3 are the two biggest sites on this subject, and both have extensive knowledge bases and forums.
