I was reading this: ""This TiVo DVR is most suitable for use in a cable TV/standard definition TV environment. It also works perfectly for DirecTV and DISH environments, but unless the household also has cable TV (analog) it will not be able to record two programs at once. But, like all TiVo DVRs, you can still watch one pre-recorded program while recording live TV."" And... I have no idea how this works now. I was thinking of getting a Dual-Tuner SAT box and a new Dual-Tuner TIVO. When this is hooked-up the TIVO sorta takes over the sat box/cable box... and the signal is even coming from the TIVO to the tv too. So if you don't have some sorta HD output or HD TIVO isn't the sat HD box just going to waste since it's just going further and further down the high quality-wise as it goes from the HD sat box, to the TIVO, and back out the TIVO using RCA jacks (or even if you use component/hdmi it might not matter) back to your TV. I don't understand what I quoted above either. Are you not able to record OR watch on the 2nd tuner on the TIVO without analog cable (non-sat)? I like the idea of being able to watch in case I'm recording. And I've read before about the 2nd tuner only being able to do analog channels (1-99 or so?) but I never heard before having to have cable and sat to do it. BUT above it really just talks about only being able to RECORD 2 channels at once with cable also in the house. It's all very confusing. I'm not really sure not only how it would all be hooked-up BUT how it actually works if you have a dual-tuner HD SAT box and a dual-tuner TIVO. I've been researching whether to go with Dish or DTV for weeks, and now researching all the thing you can and can't do, what disadvantages there are with certain sat boxes, etc. It's driving me nuts. IF the sat companies just had the export to a pc feature I might just go with their dvr just to simplify my life.
