still use the SE DVD for things like the final space battle becaues the space shots are better corrected, but even then, perhaps some form of overlay is going to be needed because of how the laser blasts have been meddled with and the stars wiped out.
using the 97 SE means we've got something that is better color corrected and sharper than the OT LD. then use the minimal amount of OT LD footage to correct back to the OT cut.
taken as a whole that should then give us OT visuals with advanced sound fx.
