assassin's creed freezing? help

the sound always pauses during the voice acting parts and the mouths keep moving then the voice starts of where it left off and doesn't line up with the mouths does this happen to you to?
Only a few weeks on ps3 warrenty.

I never had that happen.

Also, technically, I neve had the game "freeze" on me either.

Though I have had 2 times now that game gets locked on the loading screens. I can still run around and all that stuff in the loading area, but the next area would just never load, so I would be stuck running around forever, hehe. Luckily due to auto-save, I usually never lose more then 2 minutes from it.

That has never happened to me
