As far as I know these are not available anywhere. I planned to rip these a while ago and even started to buy some capture equipment to do this but I kind of lost my motivation because of missing frames when I tried to sync my captures to the gout dvds.
I planned to create DVDs that are a combination of the french and german PAL laserdiscs and includes the 1995 german, french and english LD PCM audio and openings crawls. I have the required equipment, tools and laserdiscs but currently not the free time to do this the way I planned.
I could make some simple menuless DVD preservations of the german LDs if people are interested, but I still want to do it the right way some time in the future.
