Not sure but i don't think this is the first pal laserdisc preservation on these boards for the special edition.
I think i have discs from some person who did a capture.
I will have to dig them out and see. I know they were done a few years back so the quality is probably not as good as yours.
*Edit to post. The Grinder edition of star wars i have was the oot PAL.
So i guess your transfer is the first PAL special edition laserdisc capture as far as i know. The PAL DVB G'kar is not laserdisc so does not count in this equation.
