There is NO WAY to receive DVB-S2 with DVB-S equipment. DVB-S2 uses a completely different modulation (8PSK in most configurations) and error correction. See dvb.org for the specifications. There is a compatibility mode of DVB-S2 achieved by Hierarchical Modulation, but this won't be used for the new HD-channels since it raises the complexity and costs of transmission. Regards, Alain
