Hello, my first post

I’ve got a lot of free time , so I’ve decided to re-edit the prequels (and later the OT) to match their theatrical versions.
But I need your small help here.

Episode I - I know I have to remove the “air taxi” sequence, and new shots from the podrace. But where there also any sound changes ? I have the original version recorded from TV with slovak audio, so I can compare the video changes, but not audio.

Episode II - My “tv-broadcast” VHS is identical to the official DVD . What does it mean ? I don’t believe Lucas didn’t do ANY changes to this movie. Please if you know about ANY video/audio changes for E2, please help me.

Episode III - the same.

Thanks
