I have a BDP S300, one of the first generation ones. I got it at Fry's on Black Friday 2007. All of a sudden, I am getting a "Cannot play this disc" message whenever I put in any kind of CD, be it a Blu Ray, DVD, or even a CD. Last night, I watched both a Blu Ray and a DVD, so I don't know where this problem is coming from. I thought that it could be a firmware problem, but when I burned the firmware update onto the CD and put it into the player, I got the same "Cannot play this disc" message. Anyone know if there is a solution?
