I don’t know what encryption system is used, but the box needs to have a CAM slot or card slot. Web search should establish which encryption, then further searches may reveal a suitable CAM and or card that can be programmed. Beware if buying pre-programmed boxes off the web, they don't work for long
Even if you achieve this the encryption “keys” are usually changed regularly by the broadcaster in order to stop the piracy of their products, hence you may end up having to constantly reprogramme the CAM and or the card.
I used to do this years ago to get Scandinavian film Sat. channels but got tired of the weekly or less reprogramming.
FTA is the way halafu for premium content, torrent at work or see your friendly movie guy in your neighborhood. Netflix is cheap if you have good internet and many people are sharing accounts. Showmax pia naskia ni bei nafuu.
