Well, one of them isn’t a different take, just a different mix and it was repeated in the SE mix (at least the 2011 BR). That is when Luke and co arrive in Mos Eisley and confront the Stormtroopers. The Stormtrooper lines are spaced differently. The the two very noticable ones are when Threepio and R2 are hiding after the Cantina and the Stormtroopers come knocking but find it locked. That is a completely different take and might be a different person. Then after Leia escapes, the officer who calls Tarkin in the Briefing room uses his name and the take is different. I’ve heard a variety of lines are different, but I’ve never been able to hear the difference.
