I see absolutely nothing unusual in the R1/widescreen "Superman Returns" release that should cause any of the discussed programs to have the slightest problem with it. Just for fun, I ran my dvd of this title through DVDDeCryptor 3540 (yeah - that old program that many folks erected headstones over when LighteningUK dropped development). It processed the complete dvd with nary a hesitation (and no PSL needed) and DVDShrink handles the created files just fine.
