There really isn't much on the Bandai release in terms of extras. I haven't done too much fiddling with mine, but it looks like sub only, Japanese audio. As for extras, basically just clean (textless) opening and closing credits. It's pretty cut and dry.
Personally I think the effort for the Dub was anything but decent. The Japanese actors all had passion and enthusiasm behind their lines. The US voice actors really sounded like they were reading off the paper.
