For background, here’s a previous thread comparing TiVo with Comcast’s DVR.
They have two HD models available. If she’s not planning on keeping a lot of stuff for a long time, the basic $99 model ought to do the job. They claim “up to” 45 hours of storage on the hard drive, but that assumes you will select the lowest image quality; if you select best image quality, the available storage space will be quite a bit less, maybe 20 hours or so. You’ll likely be surprised at how fast you use up the available space, though; I’d strongly recommend getting the larger-capacity unit.
My experience programming a VCR is like this:
You first have to look up the time and channel for the program you’re interested in, then fire up the TV and VCR and set the TV so you can see what the VCR’s on-screen menus are showing you, and then twiddle with the menus to set a start time, a stop time, and a channel, and then you have to make sure you have a cassette in the VCR and rewound properly. To watch your program, you have to fire up your VCR, rewind the tape to the right point, set the TV to the correct channel/input so that it’s showing you the VCR’s output, and then press play. Note that you cannot watch a show you recorded earlier while the VCR is busy recording a program (unless you happen to have a dual-drive VCR).
My experience with using TiVo for the past six years is more like this:
Fire up the TV. The TV is always receiving its output from the TiVo, so immediately you’re ready to start setting up the recording. You press the “guide” button on the remote; it puts a list of channels and current/future programs on screen. Using the remote, you move the cursor to the program you’d like to record, then you press the record button (alternative: if you don’t know when/what channel your program is on, you can type in the title and TiVo will search/find it for you). If you want to record every episode of that program (with or without repeats), you can select “get a season pass,” and it will do just that without any further input from you; it’ll automatically record every future episode of this program until you tell it to stop. When you want to watch one of the shows you’ve already recorded, you press two buttons on the remote, and then you’re looking at a list of shows on your hard drive; cursor-down to your show, press play. Note that you can watch shows you’ve recorded earlier even while the TiVo unit is busy recording a show. You can even start watching a show before TiVo is finished recording it. Example, suppose TiVo starts recording your 1-hour show, and you start watching it about 20 minutes after it started. You can now fast-forward through all of the commercials, and you’ll finish watching the end of the show right around the time that it’s finished broadcasting.
Because your TiVo needs to constantly update its schedule information (so it knows what’s on every channel, what time shows begin/end), yes, you do need a monthly subscription with the TiVo company (and the TiVo unit needs either a phone line or a broadband internet connection to be able to receive this information). If you expect to keep it for more than about two years, then the best deal is the single payment of $500; the break-even point (compared to paying $20 per month with no commitment) is 25 months.
I think you’re talking about a dual-tuner TiVo. And yes, this is a great thing. It means that the TiVo can use one tuner to record a particular show, and you can use the other tuner to watch a different program on a different channel at the same time. or the TiVo can use both tuners to record two different shows at the same time.
Wife and I have had TiVo since 2005. We love it. Even if we don’t particularly need to time-shift a show, we still do so because it gives us the opportunity to fast-forward through commercials. We have tried ComCast’s DVR (free to borrow the DVR, and only $10 per month for service), and wanted to kill it with fire; it was a horrible, fetid piece of shit (see my post in the thread I linked to above). We gave it back to Comcast, spent $300 on the TiVo HD-XL and $500 for lifetime subscription. That tells you how crappy Comcast’s DVR was, and how awesome TiVo is.
If you personally know any friends/neighbors with TiVo, ask them for a short demo.
