I was very hesitant to activate my second Tivo Cablecard remembering the horrible experience I had the first time. But the cablecard activation this time was surprisingly painless and took less than 10 minutes. In fact my local Comcast office gave me the 2nd CableCard for free and allowed a self-install. I was shocked . I called up my CableCARD activations - (877) 405-2298. I think all it matters is to call the right number and hope to get a right person.
