I thought a HDTV stream was about 8Mb/sec, if it's MPEG4 compressed. I could be wrong though.

Is the quoted 200Mb/sec the uncompressed data rate? Nobody would ever broadcast this. I doubt Sky will be broadcasting 100+ channels x 200Mb/sec, as that would need a throughput of over 20Gb/sec! I'm not sure if there's enough spectrum in the world to take this lot raining down from their satellite!
