Actually no because to build a pc that can record two HDTV programs at once would require nice video cards not to mention a dedicated box as well as nice dual processors and a large hard drive. Even a rig like that would cost over $699 and wouldn't be capable of watching a program while it's recording 2 shows unless you have a monster of a pc. Most importantly you don't have the ease of use of a tivo (the tivo service is unparrelled) It's well worth the money. It's hard to explain to someone who's never seen it or used it. It's like going from analog cable to HDTV or dialup to broadband. Until you experience it you won't understand. Tivo frees you up to do everything and anything you want without having to worry about missing any show you would like to watch. Pausing your show when your son calls from college and resuming it whenever you go back to it exactly where you left off is priceless. Never planning around your shows.
Most powerful HDTV video capture cards will skip some frames and have trouble coming close to the quality of a tivo series 3. Also the OTA reception is far superior to most stand alone OTA HDTV tuners not to mention the ability to remove channels from your lineup that you don't watch and never want to flip to.
Bzzzzzzzzzzzzzzzzzzzzttt.... What is HDTV? HDTV is *broadcasted digitally*. Your PC doesn't need to encode anything. It simply needs to write the stream to disk. I've got a MythTV with 3 ATSC (over the air) HDTV tuners and it works great. I can record and watch at the same time. No big deal. I don't plan around my shows -- I tell MythTV what I want recorded and it gets done. Pause, commercial skip, etc. No problem.
Minimum you'd need for HDTV is ~ 2.8 Ghz and accelerated playback via XvMC on nVidia is helpful. So a Celeron D 340, a couple of hard drives, a couple of $40 ATSC tuners (see eBay for Air2PC), a nVidia MX4000/FX5200/6200 card with whatever output you want, and MythTV and you're golden.
Of course it takes time to setup. MythTV is version 0.20. Not as polished as Tivo but can do much more. All trade offs. But it is certainly possible.
