My other option is to include the LD rip I have on the same Blu-ray disc as a bonus à la Star Wars (or how it should have been done, anyway). If somebody here is interested to re-capture the LD with the appropriate device & settings, I think it'll help in both ways.
So, what do you think ? Continue the extensieve work to get something close out of the 3d version, of just put the two versions together (and other goodies) and be done with this project ?
