There is also World Trade Center, VC-1 + EAC3 1536 kbps on HD-DVD VS Mpeg2 AC3 640 on Blu-Ray.
Other paramount HD-DVD have the same difference with Blu-Ray
Space Cowboy HD DVD (VC-1) is a little sharper than the first BR (Mpeg2).
I’m looking for the HD-DVD version of Corpse Bride, and The Last Starfighter.
I have a lot of HD-DVD if people are interested.
