email warner brothers and ask for this show on TV and DVD
So, in addition to voting at Tvshowsondvd.com I also found the customer service site for Warner Brothers, who own the rights to the Hogan Family. They don't have the customer service link on their regular website, so here it is

I don't know if emailing them will help or not, but I don't think it can hurt.
Also, regarding Tvshowsondvd.com, the guy there has said that if individual users create multiple accounts to vote for the show more than once, he'll pull The Hogan Family from the voting. Just FYI.
