You can also check with your local cable company. They are now offering DVR's, which is the same thing as a Tivo. This is info from my cable company, Adelphia:

DVR
Pause live TV
Never miss your favorite programs
Watch one program while recording another
No equipment to buy

Now you can watch what you want when you want. With Adelphia Digital Video Recorder (DVR) you can finally take control of your TV and set your own viewing schedule. The built-in DVR lets you control live TV or rewind the program you're watching to create your own instant replays any time you want. You can also record your favorite programs directly from the integrated program guide without the need for video tapes or confusing VCR settings. In a single command, you can set your DVR to record a season's worth of episodes of your favorite program. You'll never watch TV the same way again.
