i have lots of s10`s with the same problem.
its a board problem.
my sugestion is a F3,F4 or F5 they all the same and the board is very good.
but if you could aford an extra 60.00 to 100.00 then buy an enigma2 box like dm800 or vudu.
its not just the price but also the time it takes to build channell list and get emu`s to work on the F`s unlike the enigma2`s there will always be support.
adios...
