Daria did get a couple of compilation DVDs released, actually; but no season set.
Re: Filmation and BCI--- BCI released most of what they were allowed to; only a couple of sets never came out. All the other Filmation shows have other rights owners.
Tarzan is slated to appear on Warner's Saturday Morning 1970s set, though I had assumed that the Burroughs estate would have an interest in the show.
Oh, yeah--- Dexter's lab would be great. I find it very odd that Warner hasn't exploited that show at all.
