Normally all of the satellite manufactures are required to comply not only with the DVB standards! but also that of the storage and removal of Digital information, please do not forget those very nice people in Hollywood, who would like to continue to make money.
Normally the file (movie etc) will be stored in an MPEG 2 coded format however in a majority of systems there is a keyed coded sequence that prevents removal of the stored information to a normal PC system.
Normally the "drives formating condition" additionally prevents the reading of the drive when is is configured to a linux or windows system.
Kind Regards
