Problems with Tuning Adapter

The move that Cox has had underway for quite a while (moving general channels from broadcast to SDV) made it impossible for me to view approximately 50 channels. Neither of my DVRs (Tivo and Moxi) worked well with the provided Cisco Tuning Adapters (the technicians couldn't/wouldn't diagnose), so these channels weren't available with or without the Cisco TAs. The Cisco TAs also limited recording from 4 simultaneous programs to 2 simultaneous programs.
