6. General - What are the benefits of a dual-tuner receiver over a single tuner receiver?
The dual-tuner version of ZapperBox has the following advantages:
1. While one tuner is being used to watch TV, the other tuner is used in the background to keep updating guide data being received over the air on other frequencies. This way, whenever you press the guide button, you see the most current guide data. See FAQ #45 for a much more detailed description of how guide data works.
2. The second tuner can be used to record a program that is not currently being watched.
3. A dual tuner box can record two programs simultaneously while a third pre-recorded program is being watched. A single-tuner device can record one program at a time while another pre-recorded program is being watched.
