- The number of tuners: Standalone units have only one tuner, while those built specifically for satellite or cable usually have two. This allows you to record two shows at once.
- No extra hardware needed: Everything is included in one box with cable or satellite TiVos. There's no need for an external tuner box for adavnced TV services.
- Record the direct video signal with no conversions: Even with digital cable or satellite service, a standalone TiVo records the analog output of the tuner box. With a cable or satellite TiVo, you record the video directly off the incoming TV signal. In the case of satellite, this means everything stays digital from beginning to end.
- No need to control an external box: Since the tuners and guide are inside the DVR, you don't need to worry about controlling an external box.
