I don't have any solutions, but I have more information, as I've encountered many problems with this (and other movies) recently.

The problems are with Sony DVD's that are protected with the new Bad Sectors on DVD copy protection.

The video's I've found afflicted are Hitch, House of Flying Daggers and Kung-Fu Hustle.

Mplayer is able to play the movies and rips from them without difficulty, however, if you try to play the AC3 stream from these videos with a52dec, it will squip the first several frames (this is apparently normal) then go mad with error messages.  

As far as I can tell, there is some 'junk' at the start of the AC3 streams with these movies that causes all kinds of headaches, but it only occures at the very start of the stream.
