The change that irks me the most is the change from a classic: (from Empire)

Luke: (after R2 got spat out by Dagobah monster) You're lucky you don't taste too good.

to the standard and less fun:

Luke: (after R2 got spat out by Dagobah monster) You're lucky you got out of there.

That irked me more than Jabba in ANH or Greedo getting the first shot.

Mielr is right. The "your lucky you got out of there" line is from the theatrical 70mm mix. The "Your lucky you don't taste very good" is from the 35mm version. the 35mm version is more well-known because it was the sound mix released on video. But the DVD line is actually original as well, even if it isn't as funny.
