Advertisements I have had the hd about 2 weeks (had the old number 1 dial up kind, no problem for years). This reboots itself - for no reason, freezes, shows frames of motion that shouldn't do that kind of motion. Has endless problems with the two cable cards (it keeps showing no channel on certain channels - at times only half the channels will show up - only a reboot gets them back. (Comcast cable in NJ). We are getting two new cable cards installed tonight in case it is that. Tivo said, yes they heard of this complaint and are working on a software update, but have no idea when it will be ready. I bought from Tivo at the same time a 500 g external hard drive that I had to return to them (they told me they didn't do exchanges) because it wouldn't work (the woman at Tivo said they heard of that also). I bought from Amazon another hard drive (same kind) and it works, but of course, it really doesn't because the whole thing doesn't work. I have 2 weeks to decide whether or not to return it, which I am very tempted to do and to just use a Comcast DVR, which of course isn't Tivo, but it works (I have one in another room).
