Yeah. In the first ep there's like a 5 second moment toward the end where the dub changes to Japanese and then back again. It's the weirdest error to not catch.
Also, even though Bandai Ent has obviously created real subtitles already it has hearing impaired dubtitles in place of real subs.
At least the video seems quite good.
Hopefully the 2nd Gig set remains error free, I haven't heard any complaints about that one yet and I haven't had time to check mine out yet.
They really need to offer replacements. Anchor Bay and therefore Starz/Manga is owned by Lionsgate, they can totally afford it.
