Well even if you do buy a MP4 player from the United States Problems can still strike. I I had bought a touch screen mp4 player with a 4gb hardrive. Everythiing works well, but you know when you just pull the plug without safetly removing it could cause your files to become corrupt and not being able to access any of my files. I know how to fix this problem because I've done it.It deleted all my files and retored my directory and it's only a free demo. This worked for my MP4 player I might work the same for yours if you need to know the program just email me at brandonrhodes20@yahoo.com
