I am a Cox NoVA customer and recently bought a HD TV. When I hooked everything up to the new TV and started flipping through the channels, I saw that several of the HD movie channels would not turn on. I never looked at the channels until then since I had a SD TV. The screen would be black for several seconds and I would get an error saying something about the Tuning Adapter not being able to turn on the channel. These were for several channels that work fine on the SD version along with the additional HD movie channels. After googling the issue, I saw that other areas have reported similar problems and have cited FCC violations. Reading the "CableCARD: Know Your Rights" guide on the fcc website indicates that I am not receiving channels I should because they are not on-demand. Further googling produced an FCC ruling in 2009 that Cox had violated several FCC regulations and either ignored or partially complied with them. I did not see any followup. I called Cox and they said that I should get them and would send a signal to my tuning adapter. That did not fix it. I fear that repeat calls will only have them do the same thing several times and then give up. Has anyone else had the same problem with Cox NoVA and their tivo w/ cable cards? I want to know if there is a phrase I need to tell the Cox people so they will fix it or send it up to a higher level technician that knows what to do, or if I need to fill out an FCC violation form.
