It doesn't show up in that particular line-up tool, but it does appear in another  channel line-up tool.  When I go to the AT&T Shop section of the site and use that line-up tool, it appears.  http://www.att.com/u-verse/shop/index.jsp#fbid=JKwEJCNtKO1  There is a link to see the complete channel line-up and it appears in that one with my zip code.  I can't seem to get a good answer from tech support as to why I can't get this channel when I am paying for the HD Premium Tier.  Maybe it'll show up one day.  Who knows at this point..lol.
