I assume that worked? If not, make sure Twonky is set to "Enable sharing for new media receivers automatically" or manually provide the Oppo's MAC and IP addresses.

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.

As I have said before, that the analog outputs on the 95 sound much better than the HDMI to my Onkyo PR-SC5507 preamp. I attribute this to a) the Oppo has excellent analog outs, and b) the SC5507 is not doing a good job of handling PCM over HDMI signals.

The improvement is huge for PCM but for encoded formats, DD, DTS-HD, etc, the difference is primarily the Onkyo sound which I feel boosts the treble a bit. There is much more detail and better fuller bass.

I have full-range speakers so I do not use bass management, but if you do, than analog may not be a good choice.

I just picked up my BDP-93 about a week ago. So far I love the picture quality and just the overall setup of the player.

The one major problem I have occurred so far is that the player has freezed up on me about 5 times so far when watching a Blu ray. The Freezing occurs when I skip ahead to the next scene. 95% of the time it skips fine but once in a while the blu ray will freeze when doing so. I've noticed it the most when playing avatar on 3D.

Anyone else have this problem and is there a easy fix?

thanks,

More often than not this will be caused by a dirty or defective disc. The player will pause for an inordinately long time while seeking through bad sectors, so it might appear to be frozen. It's always recommended to clean a disc that causes issues regardless of how good it might look.

I'm interested in purchasing OPPO's BDP 93 Blu Ray Player. I know the player has 2 HDMI outputs. If I hook up HDMI1 to my receiver and HDMI2 to my TV, will the sound produced be just as good? My receiver would be a Marantz 7006. I know from what I read that the OPPO BDP 95 produces better sound, if you use the audio outputs instead of the HDMI. Why pay $1,100, when the OPPO 93 is only $499. I believe a person with $20,000 speakers would be able to tell the difference. The speakers I would use are the POLK RTI-A7s with CSI-A4 center and POLK subwoofer. I do not have this system yet,but I believe my CD's should sound as good with above system. Anyone tried the BDP-93 for CDs yet? Thanks

You need to do it the other way around. If you cable both HDMI outputs, then HDMI 1 will only carry stereo audio.

With HDMI 1 to your TV and HDMI 2 to your AVR you will get excellent sound from a decent HDMI AVR. I don't know enough about your Marantz to know what it does with HDMI audio input.

Unless you have a NEED to run HDMI directly to your TV -- for example if you have a 3D TV but your AVR won't pass 3D video, you can use the simpler single cable connection: HDMI 1 to your AVR for both audio and video, and HDMI from your AVR to your TV. But if you hook it up with two cables as I just described the audio on HDMI 2 will be identical to what you would get on HDMI 1 in the single cable arrangement.

Sorry guys, unfortunately I am not knowledgeable enough to contribute meaningfully to this topic. I just thought the article might be useful for those who are interested in reading an apparent expert's point of view on the subject of why different types of digital interconnets cause a difference in analog sound.

As for me, I just know what I hear and that's enough for me.

I am a retired audio/video professional. If folks could just see the process that is used in a professional environment to produce the aural/visuals that we consume then they would/should realize just how ridiculous calming to hear a few pico seconds of jitter is.

I sure wish that I had retained all those old Polaroid scope photos that I made doing audio analysis on the likes of Ampex ATR-104, Ampex MM-1200, AVR-1, etc.

Awesome Reel to reel man.
I only use it these days for playback. In the 80's and 90's I recorded cd mixes on reel to reel (7 1/2 inch/sec speed) tapes (when i was DJ).
I use this one:

Akai GX-215D. And within two weeks i get Akai GX-215D service-kit, to renew the rubber parts, and follow these steps..
Looking forward to use the reel to reel deck for another 20 years.
It sounds so awesome (if you keep the heads clean and demagnetised), Reel To Reel decks are ideal for some kickass electronic music (damn fat bass).
post #18311 of 26595
Anyone using this yet?

Will some of the more technically inclined memebers comment on the Speed Menus setting and how it relates to the future of the Oppo 93 when archiving to ISO?

--Bob

For encoded audio, I don't know if input jitter will matter as much since at that point it's data that has to be decoded, processed, and reconstructed as a final output PCM data. There may be enough buffering in place that it the jitter is entirely from the receiver/processor's own internal clock and not relevant to the source jitter.

However, when it comes to PCM data, where the clock going to the DAC is directly from the recovered clock from the bitstream, I definitely can hear the difference jitter makes.

--Bob

This is quite possible, but this is not the only method I've tested. I use analog out for all multi-channel material. For stereo pcm material I can choose to use analog out, spdif out to my DAC, spdif out to my receiver, hdmi out to my tv which also can go to my DAC and to the receiver. The data should be identical in all cases except maybe the last, only difference is jitter.

However, the sound from my DAC when sourced through the Audiophilleo is significantly better than when sourced by the spdif optical out on the BDP. The HDMI to tv to DAC is another slight step down from the optical out, but no where near the huge step down of the spdif compared to the Audiophilleo output. So what I'm trying to say is jitter differences are real in a PCM setup.

You might have that last statement reversed. If you are not using full range speakers, using your 95 with bass management and analog out to a pure direct mode on your pre-amp will result in continued enjoyment of the 95 DACs like how you are enjoying it. If you use bass management on the pre-amp/receiver, now you are hearing the DAC of the receiver, or the ADC/DAC pair if you use analog outs set to full range on the 95.

And what I'm trying to say is that S/PDIF is not HDMI. You can't draw any valid conclusions on how HDMI audio works from how S/PDIF audio works. And trying to draw conclusions on how HDMI audio works using a test rig that converts the HDMI audio to S/PDIF audio is simply wrong.

S/PDIF audio is a stand-alone signal, independent of any re-sync data. Not so with HDMI audio.

post #18314 of 26595
Well, I gotta say I still love this thing for playing iso 3d back ups. Just fired up Green Lantern for my son on the Oppo and he loved it. (he's 9) I currently have a 2TB drive filled with 3D blu ray iso movies. I am sure come a month or two the newer ones won't play without me updating the software (for the disc version) and I will be real sad. I plan on keeping the current firmware until a media player can come out that will RELIABLY play my 3d iso back ups. I have a Dune (among others) for all other iso blu ray files.

True Bob, my tests were not for proving HDMI better or worse, but were done to show jitter being a valid component to audio quality in a spdif pcm system.

Unfortunately I have no HDMI receiver so haven't put much thought into HDMI audio other than what I heard of it being a high jitter medium not suitable for audiophile quality music delivery. I'll read more about HDMI audio to understand it before commenting about HDMI audio quality concerns. At this point I can't say anything one way or another since I have nothing to listen with related to HDMI.

By the way, do we have a list of all the easter egg or special commands not documented in the manual?

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.
--Bob

The player powers down and i have to restart it. this is the only disc i have problem with, it´s a little annoying.
It plays ok on the ps3.
The oppo support blames the bluray chip mod and will not help.
The problem only appears if i play the movie from start to finish,
if i start in the chapter before it happens it plays fine to the end.
I have tried two different blurays from two different stores with the same result.
I will try it your way and see what happens.
post #18321 of 26595
Well obviously, if you have a modded player, at some point you will need to pull out the mod to see if that fixes the problem. You would likely have to re-install the firmware after pulling the mod to be sure you had a good firmware install to test against.

If pulling the mod fixes it, the people you need to work with are the folks that sold/installed the mod. In fact it wouldn't hurt to get in touch with them now to see if they have other reports of players with their mod powering off unexpectedly. I don't recall any such reports being posted here.

It could be, for example, that the mod you are using interferes with proper installation of the firmware. There were some early reports of that when mods first started appearing, but I believe all the mod makers have since revised their mods to eliminate such problems. Perhaps you need an update to your mod?

Did the Oppo people say they had other reports of this disc failing in players with your particular mod?

Anyway, try the firmware re-install and reset first. That's always a good first step whenever a player is acting strangely.

Thanks for the reply. The disk is spotless and was just unpacked last week, so no scratches on it any where.

Should I return the player?

I have downloaded MediaMonkey as well as Twonky to try and resolve my disconnect issues I was encountering with Windows Media Player. Perhaps some of you could help as I describe my continued problems. Main issue is that the playback is very choppy listening to Hi-Res Surround tracks and not useable and inconsistent with even CD's that I've ripped. The connection is consistently in the 80%+ region so not sure whats going on.
1) Mediamonkey- I ripped a few of my DVD-Audio's with DVD-a Extractor and they do not show up on MM.
2)Twonky- DVD-A that i have ripped do not playback well at all. its inconsistent but will generally play ok the 1st song or so then gets choppy.

Any ideas?

What containers and codecs are you using?

As an experiment, could you switch to an ethernet cable?

Do the files play correctly on local storage?

I tried reset and firmware reinstall,
now the player acts like the universal discs we had problem with in europe:

Have you checked that your region-free mod is set to the correct region for that disc after the firmware reinstall and reset. Not all discs will put up an error message if the region coding is wrong.
