B4U Movies is encrypted in nagra 1, an encryption which is totally shot to pieces.
The other encrypted channels are scrambled on both sets of satellites in a mixture of Conax, PowerVu, Videoguard and Irdeto 2.
The first 3 are totally secure so you can forget any ideas at all of watching them. Irdeto 2 has started to be opened in Europe, but is only available on certain cards.
No idea what the situation is on the Intelsat birds or Asiasat, but its probably secure as well.
So its a case of pay up or do without
