I'm sure lots of people would just love a custom firmware that kept ISO playback (the firmware files are there to play with, so I guess it's possible to compare the last ISO firmware to the current no-ISO beta and see what was removed) but, as htwaits says, it's probably anything but easy:-)
I mentioned once before that there were custom firmwares available for my old Oppo 971, and that I 'hacked' it myself to use a custom background (via a tutorial on these here forums), but that was a long time ago. The 93's firmware is bound to be both complicated and protected (Bob confirmed all firmware updates need a digital signature).

NOTE: This trick will NOT work on a commercial Blu-ray disc which happens to be all or mostly music -- either a BDMV or an AVCHD masquerading as a Blu-ray. The player will not find/list the individual music files from such a disc. Selecting the disc from Home Menu > Music will simply start the disc playing normally.

Does anyone know what the practical difference between random and shuffle is? I was switching between them the other day but couldn't tell any difference in behaviour between the two playback modes...?

Random may replay some tracks again before all tracks are played once. Shuffle plays each track once without repeats until all are played, but in a random order.

I've heard of other customized firmware for older Oppo's, for instance to enable playback of SACD ISO's burned to DVD-R discs, which some of the older players aren't capable of. However, the difference being those older Oppo players aren't continually being updated due to BD issues. Besides being more complicated and protected, I would think keeping a customized firmware continually updated would be impractical.

Roger,

If what Amir Majidimehr says is true (and if I understand him correctly), HDMI introduces much more jitter to the audio stream than S/PDIF connections. For example, as much as 41 times in the Yamaha RX-VS3900 AVR. I was just reading his article in Issue 161 of the WSR on Digital Audio.

In their bench tests, Secrets of Home Theater found no jitter at all on the HDMI from the 93 and the 95.

ETA: Hmmm. Actually I think I may have confused their report with that of one of the other bench testing outfits. I can't recall for sure at the moment which outfit published that result. If you search this thread you'll find it, or perhaps someone else here has it in mind.

IOW, if you cannot hear jitter, how does it matter how it measures?

If the DACs and analog output quality on your BDP-93 are better than your AVR, then you'd rather do bass management in the Oppo and leave the AVR to full analog mode.

HDMI out from BDP-93 to my TV, which outputs spdif to my DAC, sounds worse than a low jitter source to my DAC (audiophilleo). I presume there is jitter in play causing this rather large difference in quality. I've got the Nuforce Extreme Edition of the BDP-93 to avoid the additional jitter inherent in the transmission medium and leave the full decoding local to the one box. This also alleviates the need for me to buy an HDMI receiver and I can continue using my 7.1 channel full analog bypass mode getting good sound quality out of the Nuforce Extreme board.

As it turns out, when set that way, my Display does not Dither itself. And so I get significantly better results with Dithering turned ON.

Thank you for mentioning this! I've been playing with color space combinations trying to remove some grayscale banding (Oppo BDP-93 connected to a Duo outputting a PC resolution). Based on what you mentioned above, I set the Oppo to dither and the grayscale turned as smooth as butter. Turns out my display does not dither as well when fed it's native PC resolution (768p).

Not that I blame the Oppo (thankfully it allows me to correct this), but it's kind of a pain now that I can't use Source Direct and now have to manually switch between 1080p and 480i within the Oppo.

Anyway, thanks for bringing that up, Bob! Saved me from a nagging problem.

I do not see how that is possible, there needs to be sync between the source device and AVR, and I know that Denon and Pioneer introduced clock sync when using their products. I went back and forth on this years ago with Oppo so I do not see how this is possible unless I missed something in the HDMI 1.4 spec.

Finally, all this concern with jitter is pointless considering how room acoustics will override the best components. I would focus on the room tuning first before worrying about HDMI jitter.

Bob-
You may have been thinking of this from the Audioholics Bench Test for the 93 and 95:

"We also ran Bit Error Rate (BER) tests on both players using Dolby TrueHD and DTS HD test signals and both players produced a 0% BER which means both players delivered audio via HDMI 100% error free. Early HDMI products (ver 1.0 to 1.2) reportedly suffered from jitter related issues but HDMI ver 1.3 and above has completely eliminated jitter related issues thus ensuring bit for bit exact signal transfer from the player to the A/V receiver or processor. "

http://www.audioholics.com/reviews/t...5-on-the-bench


Not jitter related, but in the same report, there's also this:

"We measured distortion on both players HDMI outputs using a 0dBFS 96kHz / 24 bit Dolby TrueHD test signal. Both players measured identical producing distortion #s near the noise floor of our test equipment."

As others have mentioned, the firmware is protected by a digital signature. That means if you modify the firmware, the Oppo would not load it unless a new signature is generated using the secret encryption key that only Oppo has.

Its probably possible, but nobody would be able to do it without a lot of effort and special equipment (ie, you'd have to open up the oppo, possibly de-solder some parts, and program it directly).

Also, not to mention, parts of the firmware are likely encrypted to protect their secret AACS key.

Probably something else since nothing ever measures zero jitter. The effects of jitter can be heard, it just depends on how good the rest of your equipment is in resolving it, and also how good your DAC stage is at suppressing it.

Hey All;

Thanks again to everyone who keeps this going. Hopefully I will learn enough that I can be of some help to others in the future.

So just got my QNAP TS-459 Pro II up and running, and started the Twonky media server. The BDP-93 recognizes the server, but is showing the files as empty.

Here is what I have tried:

1. Restarted all devices to ensure changes were being recognized
2. Added "shared" folder to Twonky that contain movies that I want to stream
3. Verified connectivity to QNAP via my computer and I can see all shared folders and files

Any thoughts here? I don't know what else to try and change, and am hoping that I did not make the wrong choice here in believing that I would be able to play my video collection from this NAS.

Cheers~

Make sure you re-index your files before connecting to the server. The player likely can't find the files as the file index is empty to the player.
cadillac1960's Avatar cadillac1960 09:02 PM 02-13-2012
Thanks Neuromancer. Sorry to not fully understand, but do I do this (re-index files) in Twonky or on the QNAP files setup? And do you know where I would find that setting?

Very much appreciate you time and knowledge on this topic.

Been operating my Denon AVR-2112CI/BDP-93 set-up for a week or so now, very nice sounding set-up. Playing an assortment of CD's and SACD's, trying to figure out best sound configuration? I have HDMI and 2ch analog OUT's (Oppo FL/FR) connected to Denon. Quite a few adjustments between the two components.

HDMI surround is very nice using "FLAT" Audyssey mode.

I'm getting confused when selecting "Pure Direct" on Denon while playing 5.1 SACD's, I'm getting surround playback. How can this be? Does'nt the Denon default to 2ch OUT's in PURE DIRECT mode?

BDP-93 projects nice sound stage.

You're hearing the 5.1 source purely and directly.

I have an oppo bdp-93 in sweden, i have the DIY region modd installed.
I was watching A Christmas carol with Jim Carrey on blu-ray the and the player turns off at 1h 11 min.
Has anyone had trouble with that movie i also tried a second copy.
I have the new public beta firmwe installed, but have tried the last 2 official
firmwares with the same result.

You are saying the player literally powers down? Not just simply goes to Stop mode?

There's nothing a disc can do, even a faulty disc, to force the player to power down, so something else is going on and the disc is just triggering it somehow.

First turn HDMI CEC OFF in Setup to make sure the power down command is not coming from some other piece of equipment in your theater. HDMI CEC is the protocol which lets devices control each other via the HDMI connection.

If that doesn't do it, then I suggest you re-install the firmware and do a reset of the player:

1) Download a fresh copy of the current "Public Beta" firmware for your player. Unzip it on your computer and put the resulting UPG folder on a USB memory stick. Do the Eject operation in your computer (so that it finishes writing to the USB stick) and remove it from the computer.

2) Power up the Oppo and jot down your personal settings. Remove any disc in the tray.

3) In Setup, Erase Persistent Storage and then Reset Factory Defaults. When the Easy Setup Wizard finishes, power down the player.

4) Disconnect anything connected to the rear USB or eSata ports, including the Wifi stick if you are using that. Put the USB stick with the firmware in the front USB port.

5) Power up the player. It will find the firmware on the USB stick and offer to do the install. Let it do so. Note that more than one piece of firmware may be installed. When it is all done it will power down the player automatically.

6) Remove the USB stick.

7) Power up the player. Erase Persistent Storage again. Reset Factory Defaults again. When the Easy Setup Wizard finishes, power down the player.

8) Pull the wall power cord for about 10 seconds.

9) Re-attach whatever you normally use on the front and rear ports.

10) Power up the player. Re-enter your personal settings (with HDMI CEC OFF).

11) Power down the player one last time. (Settings are save during the power down cycle.)

The "extra steps" above are intended to maximize the odds that nothing can possibly survive from the prior firmware install to cause issues with the new install. It is a "belt and suspenders" way to install firmware.

Try that disc again. If you have the same problem, contact Oppo tech support as your player may need hardware service.

Since you are only having problems with that one disc, they may ask you to loan them the disc first so they can verify there really is nothing on the disc that is somehow crashing the player. But as I said, even a faulty disc should not be able to force the player to power down. If the disc is simply dropping into Stop mode unexpectedly then that is most likely an unrecoverable read error on the disc, which could mean a faulty batch of discs (it happens). If you have the unexpected Stop problem on more than one disc, then that could mean the laser lens in your optical drive needs to be cleaned.

Well I disagree. Although I know what Amir measured was correct when he measured it, I do not believe jitter is a problem of practical importance, even for audiophiles, on modern players connected via HDMI to modern AVRs of decent design.

I've long felt the fear on this was overblown. Decent AVR designs have to buffer and re-clock the input data. This is true, for example, if the AVR offers the option of adding audio sync delay on that HDMI audio input. Since HDMI audio is embedded in HDMI video, and since HDMI video has a built in re-sync on every raster line, the amount of clock drift possible in clocking the audio out of the input signal is inherently limited to what can happen in the short amount of time that passes transmitting a single raster line of video. That's just too short a time frame to be of consequence for the type of clock circuits we are talking about.

Now of course if there is a bug in the player or in the AVR then all bets are off. But barring bugs, audio jitter on HDMI is, in my opinion just not an issue with, as I said, the newest players and decent AVRs and pre-pros.

The Audioholics report cited above is saying that using a bench test which *DID* find problems in older players, they are *NOT* finding problems in the Oppo 93 and 95. This is good news.

From a practical point of view, I'm not hearing any jitter using HDMI audio from the 93 into my Anthem Statement D2v, which surprises me not at all because I know what the D2v does to buffer and reclock that input data.

I think it far more likely you have discovered a problem in how your TV takes HDMI input and turns it into S/PDIF output. I would not expect a TV's designers to have put a lot of effort into doing that right. Keep in mind, for example, that the TV can not output high bit rate HDMI audio input on that S/PDIF digital audio output due to lack of copy protection. And it is unlikely the TV is buffering and reclocking the HDMI input.

What sort of problems are you seeing? Can you describe them?

SD content, even when upscaled, is more sensitive to the correctness of the video calibration in the TV. There's no margin for error in SD content. Blu-ray is more forgiving in that regard (problems in TV calibration are not as readily seen when playing HD content). So what have you done to verify your TV is set up correctly?
