Your probably right. Would you believe 2 HD streams. Channel 287 HD preview is gone for now.

If HDNET TS is 14.62Mbps and if HDNMV is about the same, theirs plenty of room for SD on that transponder 38Mbps bandwidth. With 3 HD channels the average of the 3 would be 12.6 Mbps.
It could be, but again, SD IRDs do not have 8PSK capability, so Dish has not ever or will not ever (nor can they) mix 2 HD 8PSK signals and a SD QPSK signal on a transponder - thus your Good, Better, Best Chart has what has never been done and isn't possible with about 12 Million SD IRDs in service.
