This is just a little project of mine inspired by fellow a Ex-YouTuber, who actually tried to make videos about every single dub change in Dragon Ball Z!
I think the English dub's accuracy has increased by a great deal in these past few years and since we're getting a one week gap between every episode, it shouldn't be as difficult as the project of the above mentioned person.
Okay, for Episode 1 I wasn't able to find any major ones, but I think this one about the amount of time passed since the memories of Majin Buu were erased needs to be addressed:
Original
"Some time has passed since then"
FUNImation
"And the planet has enjoyed several more months of peace"
Significance:
The original version is extremely vague, and really, even a week would suffice as "some time". The dub changes this and while it still retains the vagueness, it erases the possibilty of the time-skip being less than a month.
EDIT: I hope everyone else can also add to the discussion, and let us know if you find any more dub changes
