Yeah, I have that set, they’re the SEs. It was released in 2000 or 2001, and the box art was designed to match the Episode I box art. The OOT was never released on VHS or laserdisc with episode numbers on the boxes, only the SEs.
Basically, anything OT with a post-1997 date is the SE, with the exception of the GOUT (and even that still has the 2004 SE as the main feature on disc 1).
