They did, if your local sd channels were on 119. That changed a while ago as I see many SL3 installs here where the sd locals are still on 119.Exactly, Directv is not going to make things any easier for Dish especially When bandwidth is already at a premium.
Only way I could see transponders given to Dish would be for wireless spectrum given to ATT in exchange.
Dish would rather have transponder space and ATT would rather have wireless frequencies.
What I never got with Directv is why they never required 110/119 as part of a standard install.
You install a slimline Dish, what difference and cost is it to use a SL3 vs a SL5 Dish
