According to one aspect, there is provided a method for parsing RASP events in a number of packets in a PVR-enabled set-top system using a software RASP parser. The method includes retrieving a first SCID from a first packet, determining if the first SCID is on a SCIDList, and determining if the first packet is scrambled if the first SCID is on the SCIDList. The method further includes retrieving a second SCID from a second packet if the first SCID is not on the SCIDList. The method further includes determining if the first packet is an auxiliary packet if the first packet is not scrambled. The method further includes checking for a bundle boundary RASP event if the first packet is scrambled. The method further includes parsing the first packet for a scrambled RASP event if the first packet is scrambled.
