FWIW, a new capture of the same 80's Brazil dub from better-quality VHS tapes is in the works, but not completed yet (still a VHS capture though, so don't expect miracles). As for the quality of one dub versus the other, it's always a matter of personal preference, and mine is to never use an SE dub unless there are no alternatives available.

I've let Dennis know that I'm not planning to include the SE dub in my personal archive (which I share with Harmy), but if people want to provide additional dubs to Harmy outside my personal archive, that's fine with me.

EDIT: And, FWIW, we have good-quality Brazilian Portuguese subtitles in Project Threepio, for those interested.
