A:Answer Hi Jay,
Tuners determine how many shows your Tablo can watch/record at once.
For instance, if you have 2-tuner Tablo your family can:
- Watch two different shows on two different screens, at the same time.
- Watch a show while recording another one.
- Record two shows at the same time.
If you go with a 4-tuner, you'll be able to watch/record more things at once.
Hope this helps.
