Knights of the Zodiac is the same that the popular anime Saint Seiya is sometimes called outside of Japan and DiC did an English dub of SS for Cartoon Network under that title. 40 episodes in all were dubbed but only 32 were ever aired in the U.S. and released on DVD(with volume 8: Brink of the Abyss, the final DVD/VHS release being extremely rare to the point that i've never even seen it on sale on Ebay or Amazon, so if anyone has it that'd be great) the final eight episodes were only ever aired on YTV in Canada, with episodes 33-36 only airing twice and 37-40 only airing once. I've also heard the dub aired in Australia(which makes sense since KOTZ also got released on DVD over there, albeit those DVDs had only 3 episodes each compared to the 4 each that the ADV Kids releases had)though information on that is more difficult to come by.

So if anyone could hook me up with those missing episodes that'd be great(and also the ones on volume 8, as i'm not holding my breath on that volume ever turning up for sale, at least not anytime soon).
