When the FCC declined to require an IP back channel, as apposed to Tuning Adapters to make CableCARD devices work with SDV, it was because it mandated that Tuning Adapters must actually work. In that same order the FCC indicated that it would make it easier for people to file complaints when things didn't work, and that if enough complaints were filed, the FCC would review the decision. Since the mandate was released in October of 2010, has the complaint process gotten any easier? I tried it myself just now and although the complaint site asked me questions about CableCARD etc, I was directed to the General Media complaint form. The fields on that form don't seem very well suited for CableCARD or Tuning Adapter complaints though.
