Seriously, it is known that there is no such hardware fault involved in this -- e.g., swapping players won't change anything. The output is simply not compatible for direct connection to the specific power amps these folks have been trying, OR there is an external source of hiss interference which is penetrating their setup, which has not yet been identified/isolated.
--Bob

I was just recalling the conversation i believe Oppo gave where they said that on some models of the 95, the output opamps had a DC offset large enough to cause problems when plugged direct into power amps, hence the change to AC coupling on the 103/105.

 

From the Oppo BDP-105 Wiki at http://wiki.oppodigital.com/index.php?title=BDP-105_Hardware_FAQ

 

The 95 and 83SE outputs were DC coupled. Why is the BDP-105 AC coupled?

 

The BDP-95 used DC coupled output, and OPPO found a few rare but annoying compatibility issues with certain amplifiers. Some amplifier may have a DC offset on its input and that has caused issues from popping noises, degraded sound to the audio board becoming damaged. OPPO selected the components carefully so that the AC coupled output can still produce excellent bass response. The capacitors used are high quality ELNA capacitors. Again this increases cost so OPPO did not make this kind of design changes without a good reason. For the unbalanced RCA stereo output, OPPO hired an audio consultant who developed a certain way to bias the components so it actually sounds and measures better than the BDP-95, but requires an AC coupled output.

Overall OPPO believes that the BDP-105 sounds slightly better than the BDP-95 due to the many design changes made in this product. In the end, one has to listen to the player to draw a conclusion. When OPPO first got the ES9018 reference design board a more than two years ago, it measured extremely well but sounded completely "dead". OPPO almost decided against using it and went back to the ES9016 until OPPO actually built our own board to test and found that the ES9018 was indeed better. Audio engineering is a combination of craft and science, and sometimes what is good in theory does not translate to good sound. OPPO's design decisions are based on many years of collective experience from their engineers and consultants, as well as test results from many revisions, and never based on cost reduction.

post #5704 of 16367
I have ben doing a lot of reading through this thread since I bought my 103 last Wednesday. Please correct me if my understanding of all this information is wrong. My understanding is that if you are using the HDMI 1 output, the Marvell processor is adding NOISE REDUCTION to both any streaming video or even a 1080P Blu-ray unless you use Source Direct, which takes the processor out of the equation. This NOISE REDUCTION is softening the picture and some people claim they put sharpness to +1 which seems to help.
Again please tell me if my understanding of all this information is wrong. One of the reasons I bought the 103 was to run my Fios signal through the 103 and use the Marvell processing, but for now i will keep using the ABT processing in my Denon AVR-4311.
I want to thank Bob and all the other experts here for their time and help in this thread.

See this from the BDP-93 FAQ: What Qdeo video processing features are implemented in the BDP-93?

The chip used in the BDP-103 adds 4k scaling but is otherwise similar. OPPO may have altered the functions used in the current player but I haven't collected the details yet.

It does support external .srt for MKV and other containers, but the encoding is restricted to the extended ascii oriented to Western Europe: Windows cp1252, similar to ISO 8859-1.

However, when a srt file is embedded into an MKV with mkvmerge the text is converted to utf8 and there is a larger available code set. I found Eastern European characters, Cyrillic, Hebrew and some Japanese.

I don't recall testing Chinese, and I don't know how complete the coverage is for the others.

Unfortunately, utf8 is not supported in external files. I've asked for that but we have no way of knowing whether it will ever happen.

Here is what it looks like... Aspen Extreme plays fine, The Aviator does not.

That's puzzling. What is the behavior when it fails? Do the files not appear in the browser, or does one not play at all when selected, or does it play with no audio?

I think mkvmerge accepts vob input. As an experiment, make MKV copies of these files and see if they play. It's a free cross-platform tool kit: http://www.bunkus.org/videotools/mkvtoolnix/

The QDEO noise reduction is still active on HDMI 1 when using Source Direct. Most of us who use the 103 as a transport for an external video processor find that very objectionable. If you want to view "clean" Source Direct and don't need the other features the QDEO offers try HDMI 2 Source Direct and pick the one you like best.

what set of rca cables are you guys using for analog output from oppo into a 7 channel amp?
post #5711 of 16367
Thanks dsinger. I hope something will be done to correct this. All I have ever read is how awesome the QDEO processor is. Again, it was one reasons I bought the 103. For the time being I will experiment with the HDMI 2 output.

Whatever cables I have lying about that are the right length. But I am not a believer in exotic cables.

The qdeo is awesome from a tech standpoint; what's objectionable is how it "thinks" and "adapts" to what it sees. Specifically the lower quality stuff the qdeo just does way too much IMO. The abt in my 83 was better for DVD as an example.

All VOB files show up in the OPPO menu and I can play them, but a handful don't play the audio, despite the audio being heard in those movies via my computer.

thank you Jazzguy for your response. I am not a big fan of exoitc cables either. I also have a bunch of rca cables laying around but not all the same length or thickness, and none of them only a meter long which would keep the install somewhat neat.


I was thinking of these

I have asked alot of questions about the oppo and I am very thankful of the knowledge base on this thread and forum.

purchasing the oppo is their an advantage going directly through oppo versus amazon?

To summarize:
  • All audio is AC3.
  • No 6-channel track plays.
  • Some 2-channel tracks do not play, but others with the same specs do.

You should write this up for OPPO support and offer them some sample files.

I'd also like to hear if an MKV version works better.

OPPO sometimes ships faster. You are automatically registered in their owner database, which brings good luck.

But Amazon has free shipping.

The contents of the box are the same either way.

My own preference for new multi-channel audio cables are those from Blue Jeans Cable. Not because they sound better but because they are well made, make a nice tight fit, are color coded for multichannel use, and are still reasonably priced. Not the very cheapest cables but of high quality and available in sets of about any length you might want.

I ordered mine from Amazon because, not only was the shipping free, but I got it next day. From Oppo it would have been 5-7 days. Depends where you are I guess.

Amazon has an excellent return policy.

There are several options in the unofficial 103 thread, which can be accessed from P. 1 of this thread.

Personally, on both my 103 and my 93 before it I used the mod from Only Best Rated, because it can be plugged in
externally using only the R232 and usb ports on the back - no opening up your Oppo and mucking with the innards.
(Although you can also install it internally if you want to later - e.g. you want to have access to on of those ports
for other reasons)

It also seems to be a little cheaper than the other mods.

You can also often find that same mod kit on ebay - I got both of mine from a seller called imegstore.com/avs digital.
(a few dollars cheaper than only best rated as well).

They also were responsive (by email) when I had questions with the version on my 93.

Only caveat - when I just checked their current ebay ad, it doesn't explicitly say "external" so you might email first
just to make sure that's still the model they're selling.

VOBSUB subtitles are supported in MKV but PGS/SUP for BR are not.

QDEO: yes, it applies to all inputs.

-Bill

I can provide some feedback regarding the WDTV Live (not play) and new 2013 Dune players .... Although each will play just about any video codec within a MKV container, HD audio is more problematic. DTS-MA is not supported on the WD Live and the 2013 dunes causes dropouts and stuttering. The new WDTV play also doesn't support mpeg2 in a MKV container. The dunes can see NFS and Samba shares, where as the WDLive can just see samba shares. Both will work with DLNA.

My advise when trying to decide a local media streamer is to consider carefully what you intend to use it for and what video and audio codecs you're files use. You may find a simple BD player suffices.

Several days with the 103 and so far all is good.
My Kuro seems to love the RGB setting with sharpness @ +1.
I finished watching Justified Season 3 Blu Ray last night.
Picture looked even better on the 103 than my old Pioneer 51FD.

I also re-watched part of Thor and wow- again- picture is rock solid.

I also tested Netflix after reading about all the issues here.
Played fine. I streamed an episode of Twilight Zone.
The first 30 seconds were pixelated then it snapped into near broadcast quality and held.
Good to know- but I bought this for much preferred Blu Ray anyway

Audio has also been super sweet.
post #5729 of 16367
Apropos the Sharpness +1 discussion, did anyone read the Oppo handbook?
Quote:
For HDMI 1, the sharpness level can be set between -16 and +16. The default is level 0, which turns off sharpness enhancement. The negative levels may be used to reduce or eliminate overly sharpened video. However, the picture may appear soft. The positive levels increase the sharpness.

Thanks.

I do want one free USB Port to plug in an external HD to access movies and TV Shows. External one would be fine.
