This truely is odd...

It's happening on both of your players, but maybe both players have a bad hard drive cable (very possible if they were RioCars). I seriously doubt that the files themselves are bad because of lame (EAC only creates wavs so that's out of the equation.)

Tony brings up a good point with FTP. That can introduce all sorts of errors if the FTP was setup incorrectly.

My cousin was getting CRC errors with most of the files he downloaded. Ends up it was a bad network card that was dropping packets.

But assuming these mp3s play fine on your computer, I'm leaning towards a hardware or network problem. Do these mp3s exist on your computer or are you accessing them across a home LAN? A bad wireless connection or network traffic could cause problems too...

Maybe reinstall 2.00 on the player?
