France has released quite a few classic films on DVD. Bringing Up Baby, The Magnificant Ambersons, Suspicion (all with 5.1 remixes and notable extras - most, though not all, in English). I notice quite a few John Wayne films have been released in France as well. All of these DVDs are PAL.
And yes, The Wizard of Oz has been released in a keep case in R4, where Warners have completely abandoned snapper cases. Again, this is a PAL release.
