There is more changes thant those 4 known changes (ex: the invasion of Naboo was rerendered with different ships, the external view of Palpatine’s office was deleted, the sound was totally remixed) , but it is probably not the point of this discussion.
Not sure what invasion scene you are talking about. I just went over the three shots of the landing craft descending and landing and not one frame has a noticeable difference. I checked the EU widescreen broadcast (which was before the changes and matches the VHS and Japanese LD) with the EU HD broadcast. Nothing with the landing craft was redone. And Palpatine’s office is part of the known change, so that isn’t something different. That change involves the transition from the preceeding and following scenes and the shots in the middle. There are only 4 known differences between the original and the DVD/EU HD broadcast.
