It looks like something is happening with these (and a few other) channels on Arabsat 26east.

The two channels (Fox series and Fox Movies - currently free to air and shoing a number of movies and US series) are currently on 11843 H.

However in the last few days another frequency has also been showing these channels:
12169 v 3/4 27500 - which is on the Badr satellite

Both Arabsat and Badr are in the same location and you will not need to have your dish repositioned - just the new frequencies input and loaded into your receiver (usually via the install menu)

It may well be that soon the channels will move from the Arabsat frequency (11843H) and move to 12169V - but nothing has been confirmed just yet...but will keep you posted.
