The R2 Porcco Rosso did have an English dub and subtitles on it s did many other Studio Ghibli discs. But I believe the dub cast is different from th R1 cast. Just like they changed the dub cast for Laputa, Castle in the Sky. The R2 and R1 of Kikki's Delivery Service was unchanged however.

I have the latest fansub of Macross DYRL downloaded either from ADC or BitHQ and it's really good quality and DL, which also made into DVD5 with Rebuilder. I would have to do some diggng,but it is possible I have a VHS copy of Clash of th Bionoids in storage.
