bluffmaster101, It sounds like you may have a hacked player. Most likely your player has a 1GB memory chip that has been programmed to read as 2GB. When you load files above the players true capacity they become corrupt or unreadable because they are being loaded to memory that does not really exist.
Here are a couple of posts that will help you check and fix the problem.
