I think you're too high there! MPEG2 SD is around 4-6Mbps, MPEG4 SD is around 2-4Mbps, MPEG4 HD is anywhere from 8 to 20Mbps, depending on how much wow factor the broadcaster is trying to give. A typical satellite TV multiplex is 20-30Mbps for 4-8 channels, depending on how much the broadcaster pays for higher bitrate, and thus higher quality.
