Their was a refilm of several special effects shots such as the fight between the Tantive IV and the Devestator(It may look like CG but it is definitly NOT CG) (VIDEO CLIP, .rm file) (

It should be easy. They're called the Special Edition. It's not really refilm, they just improved the effects. Plus they're working on an Ultimate Edition, which will be out in 2007.

Lol, its actually its the 2007 Archival Editions, some people claim that Lucas is going to change all the Stormtroopers voices to the voice of Temura Morrison (SP?), Lucas said in an interview he normally was going to do this for the 2004 DVD's but forgot to do it.
