Hey Ady... I don't know if this has been brought up before or not, but have you considered changing the way Luke says "Tatooine" at the end of the movie? Maybe it's just me, but as a kid, I never understood what he said until I finally turned the subtitles on one time. It makes it sound like he says "Tah-roo-ine" because his a is long and his second "t" is so harsh. I have no clue if this would even be possible. But maybe it sounds different on one of the sound sources you're using?
Then again, if it were up to me, I would attempt to change each of Lando's "Haaan" lines to "Han" as well. It annoys me SO much every time I hear his pronunciation.
