I thought I start of by giving new comers what each encryption systems means and what is used for by certain companies. I will post in different threads to make life easier for all satellite owners or people who will one day own a satellite system. Hope this helps since I got the information from a reliable source wikipedia.

'Mediaguard is a conditional access system for digital television developed by SECA (Société Européenne de Contrôle d'Accès), which has since become Nagra France.

Mediaguard has been on the European market since 1996. It is also used in Middle-East and Asia. Mediaguard is notably used by C a n a l+.

Manufacturers which incorporate Mediaguard into their equipment are notably Hitachi, Ltd., Humax, JVC, Kenwood Electronics, Nokia, Pace Micro Technology, Philips, Pioneer Corporation, Sagem, Samsung Electronics, Sony Corporation, Strong, Thomson, and Toshiba

The original Mediaguard system has been broken by the end of the 1990s, allegedly by rival NDS Group, which resulted in new cards being distributed to customers in 2002.'
