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
The Blu-ray has slightly better detail: http://hd.maltebauer.de/worldtradecenter_bd-vs-hd/01.html
But a new master on UHD would be preferable (not that I particularly want to watch this film again).
I’m looking for the HD-DVD version of Corpse Bride, and The Last Starfighter.
Corpse Bride is from WB, so it has the exact same video encode as the BD, and the audio is still lossy. Plus WB HD DVDs are severely prone to rot.
The Last Starfighter has a new Blu-ray coming out soon from a new 4K master, but no UHD yet.
