I took my unit to Florida for a couple of reasons. I attempted to connect to comcast with a cable card. Had many problems. Three times I asked Tivo CSR reps if I had to be connected to their server and they told me no each time. It was only when we got the elevated CSR did we find out that we had to be connected. The main reason being that their server saw me as an antennae customer. When we rebooted I had internet access with tivo box the cable card worked after 90 minutes and two cable cards later from comcast. Actually the comcast installer was very good about the whole thing. Part of the original problem was that when comcast installed the cable service they also installed the internet at the same time,consequently the tivo box was not connected to their server prior to the installing of the cable card. Now using my tivo box as a cable box and pvr and will revert back to the antennae when I return back to Toronto. Works well but the cable card is not available in Canada to the best of my knowledge as it is not supported by the cable companies There are some smaller cablecos in Canada which use TiVO...presumably through the cable-card system. However, this forum and thread deals specifically with TiVo for OTA, so let's please keep it on topic. Thank you.
