DISH network has agreed to discuss carriage of PBS HD programming. Both sides sound like they’re open to negotiation, and congresswoman Diana DeGette has even offered use of her Washington office as a meeting location. We suspect DISH will try to accommodate PBS with its proposed 15/30/60/100-percent rollout of HD locals over a four year period. Okay, so PBS is a little thin on HD material; we always like to see HD producers and broadcasters working together to bring out more programming….  Who doesn’t want to see Oscar the Grouch and Big Bird in 720p?
