PS3 Error Message: "Disc cannot be played"???

[surfdude12]

Hi,

I just got Close Encounters from Netflix, the disc is clean, I popped it in and after the PS3 read it for about 10 seconds, it went back to the XMB screen with "Disc cannot be played" with a long number 934....

I haven't updated the Ps3 with 2.2 profile yet, but just watched 3:10 to Yuma last night, and popped in The Departed after I got this message and it worked fine...anyone know what this message means?? defective disk???

BTW, I searched thread titles for "CLose Encounters" "disc cannot be displayed" and "error" but no threads were relevant, sorry if this has already been discussed...

THANKS
