Chewie is called Chiktaba (nickname Chico) only in the first movie.
In ESB and ROTJ it's Chewbacca and Chewie.
The 2004 DVD versions are the same as the old dub, but Han (Yann...) have a new actor for dubbing the Jabba's scene. It's quite jarring.
I heard the dub on the bluray are the same. But I did not see them.
