Thanks for trying to help, Doctor M.
According to a Disney discussion board in Portugal, the Portuguese edition has the Portuguese audio, and there was even a disc available on a public tracker ( but no longer seeded ) which includes English, German, Spanish and Portuguese.
I'm not sure I can post the link over here, so I might have to keep you AT BAY , but the torrent was 4,37 GB.
P.S. I just got your "Melody Time". Looking forward to it.
