You're welcome.
I found some Japanese copies for sale over at the LDDB, but there seems to be no way to contact the seller to ask about the transfers.
One website with comparison shots allegedly used the PAL disc, which has the same fleck in the same spot. So either it was burned into the print used, or they did an NSTC to PAL conversion, which seems unusual.
I was also thinking it would be nice to restore the proper WB logo for the era. The LD has the usual 90's logo plastered on. One thing the DVD got right was to use this...
This is actually from the Dirty Harry DVD, but I believe it's the same logo I saw on the Director's cut. Maybe I should have held onto it. ;)
