Are you talking about the re-released versions they made in '97 of the original films, or have they made new versions again?
I completely agree with chefelf on this one. I hate when films come in "NOW 20 MINUTES EXTRA, NEVER BEFORE SHOWN!!!". If they have to make new versions, they can't like the first verisons.
The new versions, visually, look a lot better than the originals. But where's the charm whithout the stop-motion, or the incredibly funny-looking explosion of the planet? In the new versions it looks more real, rediculous. The star wars-trilogy was recognized as revolutionary with all the fancy visual tricks, and then they have to enhace it further?? Rediculous. They should ban the re-released versions forever.
