129 is using 24 of the 32 TPs.
61.5 is using all 28 of the 28 available TPs (4 are out). The hold up is on 61.5. Now TPs 1,3,5,7,9,11,13 and 15 are emptied of available programming. They are being transitioned to spot beam. Once the spot beams get turned on 61.5 they will have 2 TPs free up: 17 and 21 since NY and Boston can move to spot beams on 1-15odd. They also have 2 more TPs free up in 11 days from Sky Angel. So 4 more TPs in the next couple weeks will give them the room they need for HD.
The delay in HD looks to be waiting for the spot beams to be turned on. They had to clear out all the TPs. Since USA & SciFi are on 110, they were not waiting on the spots. The spot beams were probably waiting on all the uplink centers to get ready... Fiber from the DMAs to the uplinks... Encoders... etc.
There is room on 129 and soon room on 61.5, just have to get those spots working. Dish is not going to put new HD on 129 before they have matching on 61.5 or too many would howl.
