Okay - I'm not sure how newsworthy this will actually be, and possibkly it warrants mentionng elsewhere on the forum - although I'm not sure where. So for now, I'll lob it here:
A few months ago, I imported RightStuf's Gundam X DVD sets, and found a fault on disc 3 of the first set. A little more than halfway through episode 14, the playback stutters noticeably, with audio cut-out.
I just received confirmation from RightStuf over on Facebook that this IS indeed a duplication error that affected discs in the first print run, and has since been fixed.
I'm going to see if I can get them to replace my faulty disc, although I'm not sure how accomodating they'll be given that I'm all the way over here in the UK and they're residents of The Republic of Trumpistan. But we'll see what happens.
