Unfortunately, you have been scammed. This is a common problem with buying these off eBay. There is a chance it can be fixed, so look around at other forums. This is a fine example of what is called 'Hacked Memory'. Over 250 people (and counting) have the same problem. It varies, but in your case, it sounds like putting more than 1.9 gb worth of media on this MP4 will make the chip crash. I'm sorry I can't give you any links. Hope this helps. But one more thing. Learn a valuable lesson here: If it's too good to be true, it's too good to be true!
