Official OPPO BDP-93 Owner's Thread - Page 807

I havent upgraded to the latest firmware as ISO support was dropped on the 93.....so you're saying its back on the new model?

How can you tell if a disc has a DD+ core? It would presumably be converted on the fly to DD for S/PDIF, and the disc itself will not offer the user access to the core. I'd like to buy/test a title with DD+ core. Can you let me know which have it? Thanks!

No, but with the addition of SMB access, it's possible to mount a Blu-ray ISO and play it via a SMB share. Only one ISO at a time can be mounted though. It's nowhere near as versatile as ISO playback on the 93/95, but it's at least possible.

Also, it only works with Blu-ray, not DVD-A or DVD-V.

I began buying up as many DVD-As as I could when it became evident that the format was becoming obsolete. Not only am I a big fan of surround sound, but many times the hi-rez stereo layers that are included are superior to their redbook CD counterparts. Many of these discs are long ago OOP and if you can find them, they are outrageously priced. I lost one DVD-A when I mishandled it when I was ambushed by my then 8-yr. old as I was removing it from a disc tray. Cost me $85 to replace. These days, it would probably run into the hundreds.

Fortunately, there's even been a bit of an uptick in DVD-A releases lately, and there are some exquisite recordings being released (e.g. King Crimson catalog).

True, and there has been a noticeable downtick in my bank account balance. I'm a big fan of rock re-issues on DVD-A!

I've found an archive for some of this OOP multichannel material, so I, again, understand the appeal.

Blairy, FLACs on your phone?! Seems overkill but I guess that depends on the application. For mobility or portability, I convert to the aformentioned Opus for amazing sound quality at 64 kbps.

Thanks for the reply. It seems strange though as out of the over 500 CDs I have in my collection, some going all the way back to when Compact Disc first came out as a format, I have never had one go bad on me.

Am I lucky?

I know what you mean about out of print discs being way expensive.

Same here way over a 1000 discs ripped with EAC many from the 80s. Never had one not rip. A few had errors that usually went away if I cleaned the disc or left EAC chew at it very slowly.

CDs can and do go bad without external physical damage. The foil/dye layer deteriorates over time. Some are worse than others. IIRC, it might be the Smithsonian Institute that was/is conducting long-term testing of CD longevity (caught it on a documentary). They had some CDs over 25 years old that were fine, some that began failing to read after about 10 years. Some CD-Rs that would have read errors after 3-5 years (I have one of those. You can visually see the erosion of the foil layer).

]So no I have it on HDMI 1, with all signals at 1080p.
I have Secondary Audio Off, I will know soon enough what the culprit truly is.
As I know that the player, nor either HDMI output, or my other equipment is the problem.
It invariably must be some setting gumming up the works…


UPDATE

After having the video set at HDMI 1 at all signals 1080p for 90 minutes the issue manifested.
Yes so the issue manifests if you don't have the player set at SOURCE DIRECT.



Proving the culprit is without a doubt, the Qdeo chip.

Using HDMI1 and the latest official firmware, I noticed I could not zoom (operation not permitted icon) on the Japanese BD for Kiki's Delivery Service. Zoom has worked fine for me in the past, including on BD-Java titles. Possibly a new variant not accounted for?

Make sure you are not using Source Direct (as that bypasses the processing which implements Zoom), and that you have HDMI 1 set as your Primary Output for video.

If that doesn't give you an easy answer, send the disc details (including the bar code number from the packaging) to OPPO Tech Support.

No source direct, HDMI1 is primary. I'll go ahead and contact support after a little more head-scratching. And I thought my days of contacting support on this thing were over...

When I play back m2ts files from my network, whenever I press FF or REW, followed by Play, subtitles appear on the screen. These are still OFF in the subtitles menu selection. The only way to get rid, is to select Subtitles, and then turn it OFF.

I know this sounds similar to the fix in the old firmware, but I don't hear anyone else mentioning this. It's not a biggie for me. But any ideas?

Oppo suggested I redo the firmware, I did, and no difference.

Also, when I just press Stop during playback, followed by Play to resume, the subtitles appear, but the info bar actually tells me so in this scenario.

(running latest EU firmware, Twonky is the server).

Thanks,

Check in Setup > Device Setup > Languages to see if you have Subtitles defaulted to OFF or to something else.
--Bob

Player, Disc, and Audio are all English, with Subtitles OFF.

I only noticed this when I updated firmware via Internet a while ago. I repeated the Update via USB, if any of this is relative.

Are you sure about that.

I just watched Eastern Promises off of my HD-DVD just a couple of weeks ago and I was playing the DD+ track through Toslink SPDIF just fine.

w|1,
You should probably contact OPPO Tech Support with the details. I'm pretty sure this problem is considered "fixed" in the newest firmware.
--Bob

Yes, I followed up the original email today, I think they wanted to make sure there wasn't a problem with my firmware somehow. I was looking to hear if any body else has experienced this too, so I could feedback further.

Let me know if anybody has seen similar, thanks Bob.

Wayne.

^ The only thing I can think of is that somehow the fix didn't make it into the European version of the firmware, but that's not very likely.

It's also possible, I suppose, that there's something special about the particular files you are playing. OPPO may need a copy of one.
--Bob

I probably should have used different words in my comment.

My understanding is that SPDIF is designed to support stereo PCM data and compressed data streams. This puts the upper limit at roughly 1.5Mbps, although I'm sure the standard could have been tweaked to support much more than that, especially for optical.

DD+ supports a range of bitrates from 32kbps to 6Mbps, so standard SPDIF would not be able to reliably support playback at the higher bitrates.

I am not surprised that a DD+ soundtrack can be played via SPDIF if the bitrate is low enough, as I was always surprised why they limited it to 640kbps for DD when it was capable of 1.5Mbps for stereo PCM. Someone will probably tell me that Dolby consider bitrates above 640kbps for DD5.1 to offer diminishing returns in quality. Are you sure the HD-DVD player isn't stripping DD+ back to DD over SPDIF?

For obvious reasons, SPDIF could not be used for all DD+ tracks, so I'm guessing it was safer and simpler to give the impression that DD+ is generally not supported over SPDIF.

In reality, I'm sure SPDIF could have been used for Bluray with some tweaks, but the industry does like migrating to new platforms before reaching end of life of existing ones. DVD was never leveraged to its full potential before being superseded by Bluray.

I could be wrong, but I had a feeling DD+ is similar to a DD core plus extensions (which makes it relatively easy to strip DD+ back to DD). Consequently, there seems to be little point in having a core + extensions as a companion soundtrack to TrueHD, especially if one can not go over 1.5Mbps. If this was investigated further, I expect one would find that the industry considered a 640kbps DD soundtrack to be more than adequate if not using the TrueHD track and fully supported by SPDIF and consumer decoders: the same could probably not be said of DD+.

Aforementioned BluRays w/Audio dropouts:
Pages 60 to 65 are somewhat confusing to me, particularly pg 63 (SA audio set to 'off') versus pg 64. Assuming I have a suitable AVR, wouldn't HDMI / LPCM be the preferred 'default' so to speak?

Kind Regards

Yes, S/PDIF is used for 2.3 Mbps (48/24), and even higher than that with 2x or 4x sample rates.
DD+ soundtracks are never played over S/PDIF in native form. They are converted to 640 kbps DD to ensure compatibility with anything with a DD decoder.
It requires more memory, and back in the day that was a costly issue for DVD players and STBs.
It is.
It's not quite like that. The audio framing is the same, and much of the coding is the same, but there is no regular DD inside. Instead, DD+ was designed to be easily translated (certain portions decoded and re-encoded) to DD. It essentially prevents the usual lossy degradation that happens when two lossy codecs are cascaded.

So, Ian, does this mean there are no BDs with TrueHD/DD+ after all?

Thanks for the clarifications: it was difficult finding definitive information about SPDIF.

In answer to your question, the following is a copy of a scan of "Finding Nemo" Bluray (not mine and I don't know which region this is from, but the original poster was having problems with this title and "Brave" which is why they looked at what was on the disc):

Oops, it looks like I am in error: I have been interpreting EX to mean "extensions" or an acronym for DD+ when in reality EX in this situation means "matrixed rear channel" and not DD+. In this situation, DD+ would be identified by E-AC3.

So, it looks like there aren't DD+ soundtracks after all.

My apologies for leading people astray.

This is such a huge thread and the new search engine leaves something to be desired. so....
I'll ask this question knowing it's probably answered here somewhere

I have both HDMI outs connected to 2 different receivers. When both are connected, does one downsample all tracks to 2 ch PCM? HDMI 1 is the primary and used to bitstream perfectly and I could also switch back & forth from bitstream to decoded PCM with a problem.

Now, 1 of the outputs passes both hi-rez bitstream & PCM just fine but the other seems stuck on 2 ch PCM, not even 7.1 PCM. And changing the audio format doesn't do anything to that output.

Checked the manual and I couldn't find any documentation of how the audio using both outs is handled.

The FAQ says:

Are there any restrictions on using both HDMI outputs at the same time?

• You can get 3D video on either HDMI1 or HDMI2, but not both at the same time.
• When HDMI2 is active, audio on HDMI1 will be downmixed to stereo.

I have oppo 93 connected to a Kuro9g through HDMI. No sinto amplifier.

Audio HDMI -> LPCM
dynamic range control -> on

Anyone know if 'dynamic range control' works with this setup? It seems it doesn't work..

I have Oppo 93's HDMI 1 direct to VT50 display, HDMI 2 connected to Anthem AVR for full audio capabilites (DD, Dolby TrueHD, etc). HDMI 1 is set as primary.

AFAK, DD EX really has nothing to do with DD+. Those are DD 6.1 surround tracks with a matrixed rear channel. I seem to recall some early DD-capable receivers had a lot of problems dealing with 6.1 audio. "The Phantom Menace" was quite the debugging tool back then...

Dolby Digital Plus can carry up to 7.1 discrete channels, as can TrueHD. The only disc I've seen 7.1 channel DD+ on is Dolby's "Sound of High Definition" demo disc.
