I think I have every Star Wars LD release, including a weird PAL master disc, The Keep, multiple THX1138s, Blade Runner in various versions, the SE discs, TPM, a bunch of Disney discs, I'll have to check and make a list.
But just the SW stuff and Blade Runner and THX would pretty much fill a drive.
I also have the OT on VHD discs, as well as Jaws 3D and a bunch of other VHD titles.
