It might be a licensing issue or they were made by a production company that has the rights and are asking for more money then HBO is willing to offer. I don't know if IFC still airs Mr.Show in syndication but that might play into this. I am kinda bummed the Tenacious D specials, that autopsy documentary series, any of George Carlin's many stand-up sets, and The Chris Rock Show aren't on HBO.
