I doubt any of these channels will come on any dth's other than Sun Direct because there is barely any market for these channels on other dth providers. The market for HD channels exists for more well to do people. These people may speak any language but the most common ones are english or hindi. The market does not exist in the rural areas and all. So there will be no point in adding HD channels targeted at a very small market of customers who speak tamil, telugu, etc. ADTV would make very little profit from adding any regional HD channels because the market simply does not exist, and the HD market is not targeted at a certain region, but at a certain class of people. Thats why any dth distributed evenly across India will not likely add these channels.
