D* is already using DVB-S2 for MPEG4 HD, except they use QPSK because KA band has much lower noise threshold than KU. E* can switch to DVB-S2 at any time. Their video coding is exactly like DVB-S2, but they use 8PSK with FEC Turbo Coding which gives them 10% bandwith gain over FEC Trellis coding used with DVB-S2.
