yup, that's the box/dvd i purchased, and there are five episodes on it, not four.

as for the voice acting, they've got the same voice actor for Athrun, as well as Cagalli (haven't seen any of the others, though Neo's VA is the same as Mwu's from SEED). as for the new ones... it makes me laugh that Dullindal *Durrandal now* is voiced by the guy who was Wu Fei in Wing... there was only one VA that actually striaght-up annoyed the hell out of me, and that would be that dude with the spikey red chunk in the front of his hair, so... not a major character, so i don't think it'll phase me. Gladys' VA is "eh...", but Arthur's, i think, is great, because it makes him sound like less of a twit than he did in Japanese dialogue version. he's kind of stuffy and British now. i digz.
