They do change I never paid much attention but go there on my old 622 twice a day to check local weather on the weather app.
Sunday like I said above they were sports part of they day . This morning I saw news, And now I they are hist . disc, tbs , fx
Now we just need to ask DIRT if they know the schedule if there is one.
It has been around for along time just not on Hopper. It's main use on hopper would be for the special sporting events like the Olympics, certain tennis tourney, Basketball ncaa big dance, etc. where you can watch multiple screens at once. (directv sets up mosaic channels fro special events like the masters)
For non-Hopper users it is the only channel to access the interactive apps.
As for why not in HD that is a question for Dish and has been bantered around for a while also but never replied to by dish.
