From what I understand, the "Fortune Teller Baba"-set had some issues when watching it in Japanese. The subtitle-tracks were glitched so that both of them featured the exact same text, (Japanese translations only for the most part, but one episode only had the dub-dialogue on both tracks) and in one episode, the DVD would randomly skip to the second half of an entirely different episode after the eyecatcher, though this issue was apparently fixable by starting the episode in English, and then switching to Japanese after it had started playing. Apart from that, I don't think there were any other flaws with the sets that weren't also present on the US release. (Bad video-quality, missing OP/ED-animations and no previews, in other worRAB.)
