I'm rather shocked to hear it isn't on DVD, frankly.

Warner Bros. and Fox have been in a legal pissing contest over releasing the series on video for ages. (IIRC, this made the "Return to the Batcave" reunion tv movie a tightrope act.) Thankfully, the 1966 movie was covered by a separate deal, and has enjoyed a long life on video.

Not just Fox and WB but various other entities involved with the production - George Barris retained rights to the Batmobile design and only recently started to loosen the purse strings. There's also the estates of some of the producers to deal with.
