Anyone else having problem loading Paramount or Universal BDs on PS3?

[lonerider7]

Since updating the firmware (2.60), my PS3 (og. 80g) no longer can fully load certain blu-ray titles. I've tested all 121 of the discs I own and have found that the problem is isolated to 17 titles from the studios Universal and Paramount. The discs are recognized in the XMB and will start loading but they hang before going to the initial screen. You'll see the little loading icon and then the screen goes black. You can hit the display button and see that it says it's on "Title 1" but you can't skip or ff or any other functions but stop playback. I've tried rebooting the system and turning off internet access, but that hasn't solved the problem. The titles played fine before the update, so I'm not sure what else could be causing the problem. Given it's isolated to these two studios, it sounds like a decryption issue. Maybe something in the firmware upgrade screwed up the keys to decrypt these titles? Below is a list of the problem titles.

Universal (these are all the Universal title I own, so none work):
Heroes S1
Heroes S2
King Kong
The Incredible Hulk
The Hulk
Wanted
Hellboy II
The Thing
Land of the Dead
The 40 Year Old Virgin
Serenity

Paramount (a few Paramount titles I own still load fine, these don't):
The Godfather
Event Horizon
Cloverfield
Beowulf
Indiana Jones and the Kingdom of the Crystal Skull
Iron Man

The problem is identical in all of them except in King Kong where it lets you select which version you want to watch and then hangs after that on "Title 25". I would appreciate any help or insight into this issue. I've searched the web and haven't been able to find anything on this yet, so maybe it's just my system. I've got an email in to Sony about this too. Thanks for your time.
