Hi I just got a Apex DT250a. It isnt one of my favorite boxes tested. When i go to add a channel manually. say 24 (ill use this as the virt and real # are the same) So i punch in 24.1 i get the picture, check signal strengh, Its good, i get channel info everything seems good, but it wont add it to the channel map. Doesnt seem to matter what channel i do this with. I can watch the channel, but its not in the channel lineup like it should be. Defective? just junky? Any advise? I still like my hisense 2010 the best so far.
