00:20:47-00:22:37 - When the hologram appears, an added sound effect can be heard of an metal object falling to the ground perhaps, caused by Threepio beeing startled by the whole thing. The hologram itself has a new sound effect as well as added sound distortions when the image breaks apart. When Luke removes the restraining bolt a new sound effect is added when it shuts down the hologram.

00:34:44-00:35:21 - Again the hologram of Leia gets a sort of projection sound, the static distortions were already in place in this sequence for the stereo mixes so that is nothing new this time.

01:25:02-01:25:04 - Luke's "What good will it do us if he gets himself killed?", the new dubbing sounds horrible IMO.

01:42:52-01:42:57 - "Lock S-foils in attack position." added X-wing sound effects.

01:46:08-01:46:10 - "There’s a heavy fire zone on this side." The whole line can be heard more clearly due to the mono mix dropping the stereo mixes distortions of many transmissions in the battle.
