This has been an on going saga for almost a month now and finally today Comcast informed me they aren't able to activate my cable card/Tivo Romio Plus. I've tried self installing 4 now and this 5th one the tech brought today. No matter what they try I'm stuck unable to change "Val: ?" The local affiliates come through just fine in SD and HD but everything else is "channel not authorized." I know this has to be fixable but I don't know how. Any suggestions? I live on the 18th floor of a highrise and they claim the signal is too weak for the CableCARD if that means anything..... Thanks!
