I would like to see Smithsonian back again, but with more content this time.
I also would like to see Shorts HD returned, but this time with descriptions in the Guide of what's going to be shown. I only watched Shorts HD once or twice, but I think that was mainly because the Guide never told me what was playing, and I pre-record everything.
Adding FearNet would certainly add variety to the Dish schedule. I would rather see that than more Encore channels or US-based news broadcasts. I like having a lot of choices.
One interesting channel DirecTV has that Dish doesn't have yet is MHz WorldView. I would watch that channel if it were offered. I think it probably would go in the International package, however.
Most of all, I would like it if Dish stopped taking things away from us. If they give us a channel, and people get used to it and enjoy it, then they ought to leave it alone.
