When aiming try using one of this 2 TP's which are apparently at least for me the highest powered. you might be using an unused transponder.
frec: 12050 V SR: 27500 it has the TVE mux
frec: 11884 V SR: 27500 it has de ICRT mux (identifies as RadioCuba)
and of course be extremely patient and move the dish just a bit a pause and the move a bit again , but just a bit. I am just assuming this is your first time, it took me almost the hole afternoon the first time. Your set up is ok down there in Florida.
Also I found that the Elevation scale on my Dish (a 90 cm Fortec) is like 4 degrees off (maybe because the pole is never 100 % plumb) so if it is your first time also play with elevation up and down.
BTW , the about to be release on blockbuster movie Max Payne last nite (aired on Cubavision) was good but not soo good in my opinion, who knows maybe because I could not use the Onkyo to apply some Dolby Prologic processing to the sound.
