I just purchased a new TivoHD and set it up at home. My cable company (Cablevision) is sending a cable guy on Tuesday to install the cable cards. I have a few questions though. 1. I ran the guided setup, and it asked me for my zipcode and my cable company, but it only added channels 1-99, I have many more channels than that. Why did it not add the channels above 99? I know that I need a cablecard to view them, but why are they not there at all? 2. I understand I can still watch unblocked regular channels without my cablecard, so I turned on channels 2-11 (NYC), and they looked awful, bad colors, blurry, full of static. It looked like an awful up-converted signal. I set the Tivo to Native mode, since my Samsung TV runs normally at 720p (its a DLP), but supports anything from 480i through 1080i. On my previous DVR, an awful Explorer 8300HD, the SD channels looked great, and you could tell they were SD, but they looked really good, how come on the Tivo they look awful. Could this be because my cablecards are not inserted, and once inserted the channel will get a better stream? I'm just really concerned because on my regular cable box the SD channels looked really good, I think I made the box send us the signal of 720p for every HD channel and 480i for every SD channel. I thought that for Tivo, running at Native would be the best solution? Does anyone know anything about these two issues? I would appreciate any help. P.S. I have two regular Tivo Series 2 units, neither one is connected to the HDTV, both are on older SDTV's.
