On the DUO, if just using tuner "A" but may use tuner "B" at some point, how should the tuner configuration be set for such use, in other words I don't need or want it to watch and record different seprate channels at one time, just the single input cable from dish if you know what I mean ?, is that even possible, must be ?

Oh, and what are the full set of freQ's required to scan 28.2E or will auto scan know that ?

Cheers
