Respectfully, I think your assumption is incorrect. I can sympathize with being shut out, but it is your fellow owners (who are willing and able to call day by day) who are booking up the time/unit type you want. AFAIK, Disney does not give CRO/WDWTC inventory for cash guests prior to the 11 month window.
I'm assuming that you were trying to get some type of "specialty" unit for a popular time and not calling day by day. Otherwise, it is difficult to believe that you were unable to book at the 11 month window. By "specialty" unit, I mean something like standard view or Boardwalk View at BWV or a 2 bedroom with 2 queens in the second bedroom at BCV or perhaps Christmas week at one of the smaller DVC resorts - VWL, BCV or BWV.
