Hello Im new to 4dtv, I dont know if this is the right place for this post but I would like to Watch Horsetv but Its not coming in on my unit, I get other digital channels but Htv* is not coming in I just get a black pic. anyone know how i can get it? I have looked at all the programmers i can find but none sell horsetv, alot of list/guides show it as a free channel. so im confused. plus Is there a point to the diff colors on the guide? I see blue/red/green. ect but there seems to be no pattern to the colors.
