Query: Arrived Defective

I was interested in this player due to the fact it plays OGG files (since I just made the jump to a Linux system) and that it had a line in for recording MP3's straight to memory. Problem was, every time I went to change modes to record, or use the FM radio feature, or even to change the track it was playing, the device would power off & reboot. I contacted Samsung and the recommended that I download a firmware upgrade from their website, still no improvement. I'm very disappointed with this product.
