Before their demise, Geneon released "Remix" releases of both Trigun and X. Unless its a thinpack set, which MVM like re-releasing series in, it'll be the the newer Geneon releases. I don't know if the video quality was improved in the case of Trigun but, as far as I'm aware, X only had the audio improved, just like the Cowboy Bebop re-released set only had improved audio. It would be nice if the shimmering the normal Trigun releases have goes away in the new releases...
Talking of remastered releases, my Berserk set was sent by PlayUSA today.
