I had an Austrian friend that learned all his English from star trek TNG and DS9... it was amazing :D

He'd watched the series in German and then in English and knew it well enough to pick things up.

To my ear, his English was pretty good.

That said, the 2 groups of non-native speakers that have impressed me the most are people from Sweden and Norway. I've mistaken more than one of them for native speakers (to their delight) :D

I desperately want to do this in the other direction, but I can't figure out how to stream foreign dubbed trek in the states and I don't have a DVD player anymore... It may take a bit more effort.
