p.s. incidently I remember reading an interview with the folks at Lucasfilm when the VHS remasters were first released here in the UK (the set that came out just before the 'Faces' edition, which were actually the same mastering, and came out just after the DE LD set). One of the technicians says that the scene with R2 being captured was always meant to be set at dusk, but the colouring of the previous releases hadn't been addressed. So they colour-timed (badly) that scene for the LD/VHS releases from 93.
