Hi guys, if anybody knows something about ALI chips or Hynix, please give me some help for my mp4/1GB/SD because it stops without a reason and characteres appear distorsed, i cant find the firmware

, the manufacturer is
http://www.egoman.com.cn/product/index.asp (model MD399iFOD) but there is no firmwares or real support as usually is.
i opened the case and found: a chip
ALI DRE
M566 1R B1 0643 TG05, and
Hynix Hy27 TPCB, the format video is MTV.
when i connect the mp4 to pc, it is recognized ok, gets a logical drive (g: for flash and e: for SD) but it is never visible for other programs like AMV Convert, how is it possible????

this problem was bugging me since i bought it, and now it becomes a real bug because i cant use typical utilitaries, well i got two questions, the first is most important to me, i really hope anybody can help me.
