CSN NE is and always has been on 61.5 in HD, same as NESN, SD on 119, and CONUS, not on a spotbeam.
If you decide to "move", Bruins/Celtics/Red Sox games will be blacked out on most NBA TV/NHL Network/ESPN/TBS feeds and any season ticket PPV package, except for obviously ESPN Sunday Night Baseball and it seems ESPN doesn't black out NBA coverage and neither does NBA TV.
The downside of "moving" is obviously no satellite locals and Dish is only carrying Celtics home games in HD, so any Celtics away feeds in HD on League Pass will be blacked out for you
Hmm, I am awfully sure that I saw CSN HD listed as being on 129 on Dish's website, but it sounds like that was incorrect according to you and the list.
It sounds as if getting CSN HD would not be any simple matter since I currently get 110/119/129, and probably don't have the correct dish to get 61.5???.
My sole intent is to watch Celtics games one way or another, that is the only reason I have anything more than OTA in the first place. (Even suffered through 06 and 07 on league pass before being rewarded with last season!) I don't care about the Red Sox/Bruins/Patriots at all, or locals since I get them by antenna. It's an either/or choice between moving and getting league pass (if available).
Moving sounded like a good idea when I thought it would have more HD games than LP, but if is only the home games in HD, (and if LP has more HD than expected), then it's kind of a tossup. If I can't get HD games at all because they're on 61.5, than moving would only be a last resort if League Pass never becomes available and the preview ends.
You say ESPN games aren't blacked out, are TNT games blacked out? If I can't get CSN HD and TNT games are blocked out as well, moving would be fairly unpalatable even as a last resort.
