MW1 not playing!

[DavePS3]

So... I pop in COD MW (the first one) 'cause I like replaying the sucker and lo and behold, I get a 'Yes' or 'No' option with the X underneath it. Never seen this before but I figure, Okay, maybe a firmware update thang so I press the X for Yes. Nothing happens. 10 mins go by, I then select No, press the X... nothing again. I press the PS button, end the game, the unit reboots. I eject the disc, go into the game saved stuff, delete the directories etc... pop the disc back in and... nada, same thing happens with the Yes/No options. I do the firmware upgrade on the PS3 and the game itself... no change, So, what's the deal people? Anyone running into this anomaly besides me?
