Your issues had nothing to do with SDV deployments (Cox LV does not have SDV). Your issues were related to Tivo's interpretaion of the cablecard spec. Tivo does things slightly different than every other CE manufacturer using a cablecard. Both Moto and Cisco are constantly working cablecard "work arounds" to make the MSO's happy with dealing with Tivo using customers, even though the majority of the issues are in fact Tivo specific issues.
