I now have two copies of the Casino Royal DVD and neither will play in my brand new Sony 400 disc changer. The product divisions at Sony have their heads so far up their own A...s that their products are not even compatible with each other. This issue is not isolated to the one movie.

The recommendation is, if it says Sony on the disk don't buy it. It isn't worth the hassle since most places won't return a DVD or at best will only replace it with the same defective copy.

I will try the workaround, thank you for that.
