Hi, just downgraded from AT200 to AT120 and lost a bunch of HD channels?? 1st Noticed when I went to 214 Weather channel and in SD only. Went to edit menue and only a couple channels had HD ? Finally on Dish chat had to go back to the AT200 to get the HD back. ?? Don't see any dirt members on here, but I didn't know I would loose so many HD channel. Hope this helps someone. OH, and the chat agent tried to charge me $5 to go back to AT200, I don't think they did.
