I know that the r2 Totoro and R2 Kiki have the english dubs from the 1990s, and Nausicaa only has it in japanese (I own the Nausicaa set). Laputa has the streamline dub, if I remember correctly. I kind of wish that Disney with the Ghibli films (as well as Geneon with Akira) did what Media Blasters and CPM did with their Giant Robo/Ghall Force dvds and include the original English Dub on the dvds, since they are drastically different. One of the reasons I really really like the GR dvds is for this reason.
I haven't seen Clash of the Bionoids in years, so if you could hunt it down, that'd be great.
The DYRL I have is the HK r0 dvd I got a while back that is nothing more then the R2 Jap dvd. the subs are good, which is strange for an HK dvd. lol.
