How different is the opening text? Because the original clip on Youtube had some grammar issues, if I remember correctly.

EDIT: Not Youtube, that first 2:30 on Megaupload in the main post. How much has that been changed? Because it wasn't much for an introduction to the whole saga.

EDIT 2:

Here is how I would change it (grammar/ease-of-understanding wise, not introduction-to-whole-galaxy wise):

Turmoil engulfed the Galactic Senate when several solar systems declared their intentions to leave the Galactic Republic itself, through a Separatist movement led by the mysterious, former Jedi warrior, Count Dooku.

Meanwhile, young Senator Padme Amidala, of the planet Naboo, returned to the Senate to vote on the critical issue of creating a Grand Army for the Republic, to assist the overwhelmed Jedi peace-keepers.

Twenty-two years later...

Rebel spaceships, striking from a hidden base, won their first victory against the evil Galactic Empire.

Pursued by the Empire's sinister agents, Princess Leia raced home aboard her starship, custodian of the stolen plans to the Death Star, the Empire's ultimate space station of a weapon with enough power to destroy an entire planet. These plans were the galaxy's only hope to insure safety and peace once again....

Maybe those are too long, but they're clearer and the tense is kept the same.
