It will depend on the outcome of the court rulings.If disney wins then yes other providers will have to pay twice as well.If Dish wins which imo they should then Disney will have to sell sd and hd for one price.
Which could be simplified with Dish Network only receiving the HD signal.This will be how it would work after Dish Network converts everyone on the Western Arc to MPEG4,Eastern Arc is already MPEG4.
The HD signal sends more information cleaner picture,5:1 audio.MEG4 on a SDTV is a better picture,so in my opinion MPEG2 transmissions need to be retired as a 20th Century Technology.
