Personally, some of the recent WA releases have had overly simple covers for me. I think the best Warner Archive animation covers have been for Goober and the Ghost Chasers and The Funky Phantom where they used covers for old Gold Key comic books connected to those shows:
The first 11 episodes were in BCI's volume 1: http://www.barnesandnoble.com/w/dvd-new-adventures-of-the-lone-ranger-zorro/14707037?ean=0787364724390
I was looking at a episode list for volume 2 earlier today, and I am quite sure that all of the remaining series episodes were in volume 2.
BCI released the complete series on their two OOP Lone Ranger/Zorro releases. Classic Media released the first seven episodes on a single disk. The real missing horde is the 1966-69 series. Three episodes of it were apparently on the Lone Rangers Collector's Set of the complete 1950s tv...
Yes. Classic media owns The Lone Ranger along with most of the Filmation library. BCI released most of the Lone Ranger shows in some OOP sets. There's still a single disk classic media set you can get. WHV owns Tarzan due to it's control over the character.
