Apple TV fans rejoice! Apparently, according to a thread here on AVS, the ATV2 has just added DD support for NF titles that offer it, via firmware update.
So, for those of you who were on the fence on picking one up...

Okay--my DMP-BDT110 came yesterday and I've played around with it some. It seems to run the same Netflix player as the PS3 (though it performs a bit differently) and has access to the 5.1 soundtracks and closed captions available on some titles. AFAICT, the presentation is pixel-for-pixel identical to the PS3's--it's an HTML5 app, much of which is dynamically downloaded at startup (which is why there are still multiple variants of it running on the PS3).
I ran a handful of experiments and the player apparently does not have access to 1080p encodings (or, as some would have it, the higher-bit-rate-720p encodings). It does seem to use the same "DASH"-like tech the PS3 player does, though it doesn't perform quite as well. (DASH, or "Dynamic Adaptive Streaming over HTTP", is an emerging ISO standard for adaptive bit rate video streaming; Netflix and several major tech concerns are supporting the effort--see this ). The PS3's player seems to use the adaptive bit rate streaming tech to start streams very nearly instantly (typically 3 seconds or less after pushing PLAY); the BDT110's stream start time is very average, usually 15 seconds or more. The PS3 switches between encodings of different bit rates seamlessly--you can see that it's happening, but it's so smooth it's a bit like watching the focus of a lens sharpen and soften. The BDT110's encoding switches often involve a skipped frame or two, the entire screen flashing black for a fraction of a second. During my playing around with it, conditions on my connection were never so turbulent to make it happen more than a couple of times during stream start--if I saw a lot of that, I'd probably stop watching. The algorithm might be sensitive to that possibility and have provisions to deal with it.
Here are some graphs of bandwidth consumption during Netflix play, 10 minutes of a long high-action sequence at the beginning of

Is the DMP-BDT110 bitstreaming DD+ over Netflix or just DD like the PS3?

Question: Your data show an average bitrate of 4.36 mbps for the Roku HD of the first movie. I think the highest I recall seeing on the Roku debug window on my TV was either 3.5 or 3.8. Do you have the debugging option activated on you Roku yet? What bitrate does your Roku report when it starts playing that movie?

I didn't know about the debug mode of the Roku's Netflix player--I'll try it and get back to you.

To enter Roku debug mode use the following sequence on the remote:

Unfortunately I have a 4 y/o AVR without DD+ decoding; the Panny is extracting the AC-3 core and bitstreaming that to my AVR (it's capable of processing the lossless formats and rendering them as uncompressed 7.1 PCM over HDMI, like the PS3). Others have reported getting DD+ out of it though, in the DMP-BDT110/210/3xx thread.
It's always perplexed me that the 720p stream (High/HD on the PS3) looks to be 4.4 or 4.5 Mbps when it was advertised as being 3.8 Mbps, but now I think that it could be the difference between the bit rate of the stereo sound component and that of DD+. That would make it 700 Kbps richer than whatever the old rate was. But that wouldn't seem to jibe with the Roku's average bit rate being nearly the same as the Panny's. I'm taking some stereo data on the PS3 as I type this and will follow it up with stereo on the Panny.

Yeah--it was pretty easy to find that out once you mentioned that the mode exists. I tried it last night and it said that the stream was 3.8 Mpbs. I tried to get some data last night but I couldn't reliably get 5 Mbps out of my supposedly 25 Mbps service (I have got to get around to having a chat with Cox). I'm doing it now, at 7 AM, when there should be much less contention for service from all concerned parties.

So the Roku says 3.8 mbps and your graphs say 4.4 mbps. I wonder if the difference can be attributed to header info on the packets? The Roku may be measuring the actual data payload (just the movie) and the router reporting total raw throughput? Just a guess.
