Roku is not following the the above stated specification with their Roku2 device
That statement (product feature overview) is not a set of requirements on Roku. The compatibility is provided by an extractable core, but no product is required to be able to extract that core and output it for playback on non-DD+-capable equipment. Essentially Roku 2 doesn't in any way "support" DD+ on Netflix streams--they just pass it on without processing it in any way.
I may very well be, I am only going off a post I read. It could only be referring to 5.1 audio and not the full 1080p/CC capabilities. I was not aware you could have one without the others when it came to Netflix streaming. http://www.avsforum.com/avs-vb/showt...1#post19629911
Yeah--I'm the author of that post and until recently maintained the list of Netflix titles with 5.1 sound contained in it (forever freed from that tedious task by the advent of TVandMoviesNow.com
). Nowhere in it do I state that the BDTx10s can display the 1080p Netflix encodings.
Roku has 3 models to fit any budget. There is no reason they should have skimped on their flagship model. They are not following the DD+ spec by omitting DD core.
Since last month, there are 4 models of Roku 2--LT, HD, XD and XS, priced at $50, $60, $80 and $100 respectively. Dumping S/PDIF output was a business decision on their part--they'll no doubt lose some sales to people like you who require it. I'm sure that they realize that and feel that the loss of those sales is small enough to be acceptable. Obviously they'd have to charge more for any model with S/PDIF to acheive the same profit. (I think that all previous models had an RJ45 jack for wired networking and now only the most expensive one does because they know that the vast majority of their customers will use wireless).
Whether you think it sounds "thin" is not the point, DD+ is suppose to be better than DD. No matter, discrete 6 channel digital audio is going to be superior to 2ch matrixed to 5.1 with Dolby PLII in a proper surround sound setup, even if it is only regular DD.
DD+ as used on BDs is generally 1500 Kbps or better with a 640 Kbps AC3 core--DD+ on Netflix streams is 384 Kbps altogether
--if the core is half of that it's the same bit rate as their stereo sound encoding. Having heard it (if that's actually what the PS3 is now presenting), I'm not sure that I wouldn't rather listen to the stereo.
I am not even asking for perfection, just to follow the specs and use common sense. I have been a big supporter of Roku and the pay services of Netflix/Amazon streaming. I have not used Vudu so I cannot comment on that.
Again, there's no requirement on them to process DD+; extracting the core for playback is processing. The audio spec for their device states that they provide "5.1 surround sound passthrough" on the HDMI connection. They don't process either DD+ from Netflix or DD 5.1 from Amazon (and possibly other "channels")--they simply pass it on, untouched. I just thought of this, but I'd guess that any
processing of it, including extracting the core, would require licensing from Dolby, adding to the manufacturing cost of the product.
