Okay, I'm going to come clean here...
Earlier in the thread, I mentioned that I couldn't see any lip synch problems with my Pioneer DV-414, and I was part of the UPC discussion.
As it turns out, I have subsequently watched more of the film (at the time of my original post, I only looked at the scenes that were mentioned as being problematic), and I, too, see the lip-synch problems. However, the scene where it became bad enough for me to switch to DD was when
Warning: Spoiler! (Click to show)(POSSIBLE spoiler, but I doubt anyone reading this far into this thread has not seen the movie.) the Duke was negotiating for the deed to the Moulin Rouge.
I don't believe that was mentioned before (I don't feel like going back to check right now. My apologies if it was.

)
Either way, my wife seems to be more sensitive to this than I am and noticed a few lines here and there that were off.
So at any rate, I had to get this off my chest: I do see the lip-synch problems after all.
