Anyone tested if bdmv format works?

Been ages since I owned an Oppo... had one of their early 3D players that supported ISO's, then Cinavia ended that fun via a firmware update. So, BDP-103 plays 3D MKV MKV's huh? ... via network share, or does it need to be attached storage?
Guess what... cinavia doesn't work in MKV container, subtitles are flawless.. no jukebox ...but thats ok, when im watching the movie i couldn´t care less about the jukebox..

Question.
1-What files are you trying to play on your media player(2D.mkv 3D SBS.mkv or 3D.ISO etc..) ?
3-What AV Reciever do you have?
1. Files: 2d.mkv, 3d.mkv and 3d.iso and mvc files (mts).
2. Onkyo SR501E

Money would be better spent donating to the Kodi project itself if someone was going to do this.
Near bug free Firmware takes time, especially 23.976 support.

If 23.976 is fixed, along with audio drop-outs, it'd be a great box. With Pi2 for 3D and Chromebox for 2D, you could buy a Darbee unit and still be well under Oppo's price... and get just as good benefits (proper framerates, great PQ, HD audio).

You can build a PC/Kodi less than the cost of their cheapest BD player.

"Theoretically a graphics card could support output of YCbCr. Actually the best output would be a format which is as near to the native format of the Blu-Ray disc as possible to avoid any unnecessary (and lossy) conversions. The Blu-Ray disc uses YCbCr 4:2:0. HDMI and DVI do not support YCbCr 4:2:0, but YCbCr 4:2:2 and YCbCr 4:4:4 are both supported. So outputting YCbCr is possible and would be welcome. Most TVs accept both RGB and YCbCr, so there would also be no compatability problem.
However, YCbCr output makes sense only if it's a "pure" output, without a multitude of conversions in between. If the graphics card first converts the YCbCr source to RGB, then converts it back to YCbCr for output this is actually a negative thing. Ideally the graphics card should just take the YCbCr source and output it as it is.
To my best knowledge no graphics card on the market can do this today."

Can anyone confirm ?
if it were really, with an HTPC output in YCbCr,
can be worse, because before going to Radiance the graphics card
makes a double conversion: YCbCr-->RGB-->YCbCr.
if it were really then,
is not better exit form HTPC directly in RGB, so as to eliminate a conversion ?
there is a way to verify if indeed the graphics card,
makes this double conversion or output with an "pure" YCbCr?
Thanks
P.S.
Sorry for my bad English
Yes it is true that most graphics cards - if not all - perform this double conversion.
However, if the Radiance is in the chain, sending YBC422 has some advantages and often gives better results.
Also, you have to consider what's happening after the Radiance.
If the display can process an RGB signal without first converting back to YCB422, then it might make sense to keep everything in RGB.
However, most displays do convert to YCB even when inputting RGB due to the color decoder processing, which means you go RGB -> YCB -> RGB inside the display. In that case, using RGB adds one more unnecessary conversion.
The way to check for this is to see if the color control - in the display - has any effect when inputting RGB. If it does, it means that RGB is converted to YCB inside the display for processing before being converted back to RGB internally.
While there are many possibilities, it's all down to your specific combination of source/AVR/processor/display. The Radiance prefers YCB in and out, and unless your display is able to process RGB directly or gives better results that way, YCB out usually makes most sense.
To determine whether you should output RGB or YCB from the HTPC, the best way to do so is to use the Spears & Munsil disc (either version) and check the effect of each setting on the Chroma multiburst pattern, using the HTPC to play the pattern bluray.
With my AMD 7870, RGB Full works better (I lose some chroma resolution when using YCB out) and it also gives me a slightly better peak white and on/off contrast. It's also the only pixel format that works with the PC Client 3 if you want to calibrate with Calman using patterns from the HTPC, which can be more accurate if the HTPC is your primary source (which is my case).
So try various combinations and decide what works best in your setup...

Onkyo SR501E Doesn't even have HDMI input/output, unless you upgrade your AV Receiver,none of the things you are looking for in a media player will work with your system.

I built a expensive HTPC a few years back, fanless power supply etc etc Sold it with a great Loss....the HTPC at the time it cost me the same money has the Oppo...
Please name one PC/graphic card/Android/Media player/whatever that outputs Native YCbCR (whithout RGB conversion) and with video Source direct output just want one product that does this- Native YCbCR + Source direct output..
Don't you want your benq with best picture quality ? so with feed him with chinese mess colors (like @wesk05 is showing with the Quantum analyser)
Or don't you want the best sound for your yamaha RX3050 (2000$) ? so why feed him with cheap boxes ?
The source is important...and more important is to us that have projectors and big screens

Dts and Dolby by optical spdif, no hdmi.i need optical audio out. May be I'll upgrade to a Yamaha v47x on next months.
