Do not buy any imported chinese mp4 players and USB MP3 players. I got confirmation from a memory chip manufacturer the memory chip used inside these players are manipulated. A 2 gb player is not a 2 gigabyte player but a 2 gigabit player. It will have only 256 mb memory. The sellers of these players are third grade cheaters. So beware of these products. Go for only the branded ones.
1 GB player will have 128 mb memory
2 GB player will have 256 mb memory
4 GB player will have 512 mb memory
Don't get fooled by tall claims of the money mongers. Any data exceeding the above range in the players will produce format error.
