I've got a Samsung HT-Q20 Home Cinema system and I've been trying to upgrade the firmware but no matter what I do it will not upgrade. I've gone through the instructions which I got from the Samsung website. I've downloaded the firmware from the website and I've tried putting it on a USB drive and I've also tried putting it on a DVD and even a CD put it still won't pick it up. I know I've got the USB drive formatted correctly because I use the same drive to watch DivX's. What am I doing wrong?
