I received my new TCD652160 yesterday. This morning I swapped my SA 8300HD for Tivo. I connected network, hdmi, and cable (planned on going by comcast storefront to get cablecard later this am) and plugged it in. That was about an hour ago. It has been sitting on the "Almost there. Just a few minutes more..." screen for an hour. Is this normal. Do I have a bad unit?
