Necrat said:To do two HD streams, you would need a transport rate of 9.265mbps per stream to fill the maximum usable 18.53. (Remember while the entire stream is 19.39, some bandwidth is allocated for program guide, PSIP data, and other sources). I've seen what HDTV looks like at 12mbps, and it was terrible. Horrible motion artifacts, MPEG artifacts, and , well, it wasn't pretty. At 9.265, especially with the real high quality programming on FOX HD, it would look terrible, I think.
