Your best option to legally watch South African products is to get a subscription to Showmax or Netflix.
|Showmax||Kyknet and other SA programs|
|Netflix||You might find some South African content|
VPN’s and DStv
VPN’s are legal in Germany, but infringing on copyright and accessing content that should not be available can result in legal action. Copyrights are governed by GEMA – “The Gesellschaft für musikalische Aufführungs- und mechanische Vervielfältigungsrechte (GEMA; English: Society for musical performing and mechanical reproduction rights) is a government-mandated collecting society and performance rights organization based in Germany.”
This means if you want to watch a South African program but it has no license to air in Germany, and GEMA does not earn their fees, it would be considered illegal.
