Yeah, I no longer remember what the issue was with Volume 9, but it was one of several problems Rhino had with the last few sets; they didn't seem to be giving the series the attention it needs. A lot of fans were unhappy with things like the Essentials release, which paired one new-to-dvd episode--Santa Clause Conquers the Martians--with one most fans already had on DVD, Manos. They got even unhappier when one online retailer (I no longer remember who) turned out to have an exclusive version of the set that contained a disc of the third volume of selected shorts (the first two volumes had been in earlier sets). That set of shorts has never been released again.
