What's model this MP4? For firmware

[YASLICOCUK38]

Hi,

I bought these products:
16GB 2.8" Touch screen MP4 Camera
NEW 16GB 16G 3.0" Touch Screen MP3 MP4 Player Camera Z - eBay (item 170416207508 end time Dec-18-09 02:59:08 PST)



However, many of the mp3 file will not open at all. Many video format will not open. Do you think if I perform a software update fix? For him, the product of the model should. But I do not know him ... I could not find?
Please help me get a person with emergency information ...
