My own experience, using Hotbird, Turksat and Hispasat, is that I have a problem with one frequency only (Multivision channels on Hotbird), and this only at certain times of the day (presumably when the signal isn't so strong). Picture breaks up. So I unplug my DECT phone and then it's OK. The main advantage is that the wife has to go to another room to use an ordinary phone for her interminable chatting......
