Hi Max.
Not sure if you still need them, but a while back I transferred all the extras on the superb 1997 SE Laserdisc boxed set (NTSC version). Have all the docs. and trailers etc in nice quality - used a Panasonic stand-alone DVD -recorder directly linked up to a Pioneer CLD-2950 LD player using pro-fi gold leads.
If these are any good to you I'll send you copies of the discs.
