ReplayTV 3030 Digital Video Recorder
Replay vs Tivo
Basically both units due the same thing...they record TV programs on to a 20 gigabyte hard disk. The beauty of the systems is that they are a breeze to program, you don't worry about changing or losing videotapes, and you can pause live programming if someone or thing interrupts you, and not miss  anything. The Replay was my choice because of the additional input and  outputs compared to the Tivo, and the greater cache time (30 minutes versus  about 10 hours). What that means is that should you miss part of a program,  the Tivo will overwrite that show after 30 minutes of recording versus the  Replays 10 hours. The prices are about the same after you pay for the  Tivo's lifetime programming charge.
