I love the speculating! I think Dish has all the RSN's that they used to carry still on the satellite and just turns them on for the out of market packages. If you visit James Long's listings for the 110 satellite and 129 satellite, specifically transponder 14 on 110 and transponder 26 on 129, all the FOX RSN's have an info channel in the 25000's. For example, 25436 is on 129 TP 26, and Fox Sports North used to be channel 436 and come from 129 TP 26.
Dish would have to have them for MLB EI, Center Ice and NBA League pass so no surprise they are in the system. Altogether different contract situation.
