Tonight I was watching a DVD (The Wrath Of Khan) and I stopped the machine to have dinner. I have just returned and the player gives me a prompt stating that it can't read the disc. I eject the disc and put it again-same response. I tried several other region # 1 discs and the player says the discs are unreadable. In fact, the player makes several clunking noises trying to read the disc. I put a CD in and it plays fine. The player is only a month old. Is it broken? Any thoughts would be appreciated.
