Ka, DVB-S2D, SR 30 Msps:
QPSK 3/5 35 Mbps
QPSK 2/3 39 Mbps
QPSK 4/5 47 Mbps
8PSK 3/5 52 Mbps
8PSK 2/3 is how Dish Network is getting sometimes 10 HD per transponder. See Tp1 on Echostar 3 for example: http://sathint.com/echostar-3
Though they have the luxury of a Ku band license at that location, therefore 8PSK with turbo coded FEC (2/3 instead of 3/5) is how they have much more bandwidth per transponder. If DirecTV tried 8PSK on Ka band, I'm pretty sure the rain fade would be even worse. Oh well DirecTV has to work with the cards they are dealt. Just because someone is born with a disability doesn't mean they can't live a normal life.
Dish's 8PSK 21500 2/3 modulation gives them around 40-41 megabits of transport.
