Any one know if one should be getting channels on the second tuner if the CC is missing? I've been having problems with the second CC in my TivoHD since day one. It is only getting the local SD and HD channels. The second CC doesn't have to be the one in CC2, rather the second CC activated. Anyways, I thought I had a bad CC so I went to the local Comcast store to try and swap it for a new one. I was told that I need a tech visit even though the CSR on the phone I could do the swap. So I am setup for visit #5 tmr. When I came home I noticed that I was getting channels on the tuner with the missing CC and now I'm wondering if that is right or if my TivoHD is broken? Any suggestions?
