Wendell, why are you getting so defensive? I'm just laughing at the caps for audio bit rate in the UV spec--it doesn't matter whether anyone's released a UV title with lossless audio or not. You asked for proof that the spec supported it and I gave you a link to some. I'd agree that it'll be a while before anyone offers lossless audio in a stream; VUDU's HDX video+audio is around 9 Mbps and 4+ Mbps is common for lossless audio encodes; I assume that VUDU HDX with lossless audio would average 13 Mbps or more, requiring a connection to streaming servers of around 16 Mbps to keep ahead of it.
Though VUDU's HDX video can be very nice, streaming video+audio haven't yet reached the point where it's AV-ophile stuff. As I posted earlier, I downloaded Prometheus to make sure that I wasn't affected by any dips in available bandwidth or server responsiveness, and while it was pretty nice overall, but there were easily visible encoding artifacts that I would certain hope are not part of the BD.
As for BD video encoding bit rates, you may be right about the range of the average disc, but there are plenty encoded below 20 Mbps, some of the titles. Blu-raystats.com only knows the bit rate of a subset of titles it lists (looks like about a quarter of them), but of that 2300 for which they do list video encoding bit rates, 559 were encoded at <20 Mbps. Some of the titles at lower bit rates are kind of shocking, like Harry Potter and the Goblet of Fire at 12.87 Mbps, Terminator 3: Rise of the Machines at 13.52 Mbps and Batman Begins at 13.7 Mbps. But not all encodings are equal on a per-bit-by-bit basis--encoding tech improves all the time, providing the same or better quality at lower bit rates.
