As if my stress level hasn't been high enough lately, I was watching The Mexican today, when it suddenly froze. This sort of thing has never happened to me until today, and this is with a year old Sony S560D DVD player. I first tried to return to the main menu, but the player didn't respond to any of my commands using the remote control or the buttons on the machine itself. So I proceeded to eject the disc, and put 3 other ones in, and each time, the machine read "No disc." The troubleshooting section in the manual has no real advice, and the player never did a self diagnostic check either. HELP!
