Dish is likely to have a solution, probably based on the new Slingbox Pro HD technology and something like the Slingcatcher. Or maybe they could do something QAM based. But I don't think we will ever see true ATSC modulation on a Dish box.
Dish needs a solution for this pronto. Not only are many households getting multiple HDTVs, but (if it hasn't happened already), SDTVs may lack NTSC tuners, messing up the TV2 functionality for SDTVs
Dish must implement sling catcher in their VIP series of boxes.. that's key to doing anything useful with sling.. and the 722s isn't a good idea.. should have been an option for all vip boxes..
this is one of dish's biggest faults.. creating new boxes constantly with different software on them.. it leads to their inability to adapt and grow the software as quickly as they should..
