It just occured a couple of days ago. I was unable to play the newer bd movies such as Ratatouille, 300, and Live free die Hard. Also, unable to play any PS3 games such as Assasin Creed, Uncharted, COD4, etc.
PS3 40 GB with the updated FIRMWARE :I brought this at KMART on 11-13-07.
It seems like I'm having loading issues when trying to play any PS3 games (Pretty much stops loading)
I can play all the OLDER bd movies such as Spiderman3, Species, Patriot, Stirs of Echo but not the newer ones as I mentioned above.
Also, I can play CDs and DVDs.
Call SONY customer service and they going to send a prepaid BOX for me to put the PS3. The estimate time of repair will be 15 business days.
