Go to
www.dbsforums.com and go to the dish pointing section or go to Dishnetwork's site and download their dish pointing program. The coordinates are the same for Dish and DirecTV at 119. You can also use this program for the coordinates for 110 so you can get Showtime HD. You will need to replace the standard LNB with a Sat-C version.
You can also get multi-switches from places like Parts Express.
