Official OPPO BDP-83 Owner's Thread [technical talk only] - Page 424

Gotta' love that West Coast EE education...very informative!

Neuro, it may be OT, but is it time to give us the number of original Beta testers for this player...inquiring minds would like to know. Off hand, I think there's about a dozen continuously contributing original guys on this thread, but how many original units were sent out for this process? We owe all of you a debt for the work that was done in the past!

I will comment.

People like John Sunier drive me nuts because they keep companies like Monster and their legal dept so well funded.

The real gem was this...


Now where's a double blind test to determine which player has been 'broken in'?

These people are frauds and do a disservice to the A/V community by offering their opinion as technical commentary. It's way too easy for companies to just toss free gear or advertising their way and get comments back like 'more richness and fullness' and 'more air'.

Here's a hint Mr. Sunier...if you say the analogue output on the BDP-83 sounds better than the 983H, why not research the SNR and tech specs of the analogue audio stage (resampling, DACs)? And if CD sounds largely the same on both machines, but SACD/DVD-A is much improved, why not look into the dynamic range of different medias - or even the 'hot' (boosted EQ) CD studio mixing that results in clipping on limited dynamic range CD media?

If Mr. Sunier replaced opinionated, bad poetry with some technical study, he might be less surprised that a CD does not offer the best test of analogue stages.

Unfortunately, bad poetry still sells consumer electronics and frivolous 'upgrades'.

It might not be good for advertisers, but I'm willing to hang it out there and opine that a foray into technical evaluation and double-blind studies would conclusively demonstrate that the upgraded BDP-83 analogue stage has a much bigger effect than 'carbon fiber feet' upgrades. Do I go too far?

To try get rid of all this negative energy, I'm going out to the garden now to sit in my vortex. Maybe I'll try find a good rock to put on the Oppo...any suggestions on placement...maybe igneous, crystal?

Feng Shui for your electronics...it will enrich your life (and your suppliers wallet).

The lovely and inviting Audio Theory, Setup and Chat forum is waiting for contributions: http://www.avsforum.com/avs-vb/forum...aysprune=&f=91

Very many issues that are off topic here would, I'm sure, be welcome there.

Proprog -- no worries. didn't mean to be snippy. Thanks for the help ... now the waiting for delivery begins : )

The Oppo warranty can be pruchased anytime within the 1st year of ownership, so it's not important that you purchase it now. Also, most credit card companies extend the manufacturer's warranty up to an additional year.

A number of off-topic posts have been removed and some members have lost posting privileges in this thread. Hey.. we changed the topic title for a reason.

First, I happen to know an honest reviewer. Personally, I don't believe we know all there is to know about human perception, so some of the "snake oil" might actually be on to something, and of course they may not be. Why get hot and bothered about it? Being skeptical, but open minded, I've been surprised by some of the things that made for an improvement, and surprised by some of the things that didn't. I trust my ears.

The OPPO sounds good. The 2 channel analogue out stands up well to the DAC in my Peachtree Audio NOVA amp. That says a lot considering the DAC in the NOVA is widely thought to be the best available to date.

I just tried Rise of the Lycans BD and Slumdog Millionaire BD. When each BD gets to the main menu, I can not move the cursor to select audio or start the movie. When pressing other keys they work like Setup. When you press >> you get the red circle crossed out. So the Oppo is seeing remote commands.

Anyone else having this problem? Both came from Netflix.

Hi,

I just recieved my Oppo today and currently running it. I am not sure if this has been addressed or not but there seems to be an issue with the 24p on DVD.

As I'm playing a music video with this on, there is visual tearing and skipping while the audio remains fine. If I turn this off 24p, it plays perfectly. The TV I am using is the Sony 52" XBR 5.

My question is, is it something to do with the video or there is an update.

This is the DVD I'm using - http://www.cdjapan.co.jp/detailview.html?KEY=FLCF-4238

Thanks

Finally received my Oppo today after playing tag with FedEx since last Saturday.
Looking forward to giving the Oppo a complete audition, and side by side comparison with my Panasonic BD80.
Will be looking at overall blu-ray PQ and AQ using the 7.1 analog connections via my Denon AVR 5803.
Video will be feed via HDMI to my Sony XBR6.
Speakers will be a 7.1 configuration consisting of a complete M&K S5000 system.
Will also be trying out the Oppo with my DVD-A & SACD collection, and do a comparison with my Denon 2930CI player as well.

Interesting - looks like there has been a hardware rev to support auto detection of uplinks with the SB3 because mine will certainly not work if set up like this.

Let's see - I pointed you to the FAQ which does answer the question you asked AND I gave you an answer to the question you asked. A reply that directs you to look somewhere else isn't exactly useless when that somewhere else actually contains an answer to your question . Most of the comments in the FAQ regarding the serial port were borrowed from a post by me - I don't see any point in typing the same thing again when I can just redirect someone to the FAQ.

This comment isn't directed specifically at you, but this thread is literally overflowing with people who are quite frankly too lazy to read the first post and the FAQ both of which answer probably 80% of the questions that we're seeing over and over and over again in this thread. If some of us come off as being a bit annoyed when we answer one of those questions, I think it's with good reason at this point .

I've also been dealing with a family medical emergency this week (my dad had a heart attack on Sunday), so perhaps you can forgive me if I'm a bit short with my replies at the moment.

I emailed Oppo asking a couple questions about the player's bass management over the 7.1 analog output. The first was if the redirected bass from speakers set to small was lowered 10dB before it is summed with the LFE. The second was if the player lowers the subwoofer channel an additional 5dB if it is handling the bass management (speakers set to small).


Here's what they told me------


When the player internally decodes Dolby or DTS audio, the LFE channel is already 10dB lower than the other channels. This is not attenuation by the player, but a requirement in the original encoding of the audio.

When the player does bass management and redirects bass to the subwoofer, it attenuates the redirected bass to match the -10dB LFE. This way the subwoofer output of the 7.1ch analog output is consistent with the Dolby and DTS requirements.

Under this condition, a simple 10dB boost in either the amplifier or the Subwoofer should be sufficient to handle the level alignment. It is best not to use the speaker level trim settings in the player, as the trim settings are applied in the DSP before the audio signal gets converted to analog. This digital manipulation could result in reduced dynamic range and audio resolution.

So that tells me boosting the sub channel by +10 is all that's needed, even if the player is doing the bass management. Not the +15, as we might have thought.

I hope this helps, in case anybody was still wondering about this.


BTW, if anyone cares, my initial email only asked the first question. Their response was that they didn't have definitive numbers for redirected bass and that their engineers have been tasked to perform some testing with redirected bass. That tells me they did some digging.

Hi. One of my posts was removed and I apologize for any wrong-doing, but I feel it is actually on topic. On my Macs, I can view the correct set of .VOB files in the VIDEO_TS folders for 4 specific films (Alien 1, 2, 3, 4), and play the movies using either Apple's DVD Player app or VLC app. However, if I connect the drive containing the VIDEO_TS folders to the OPPO BDP-83 via USB, I see very different files. There doesn't seem to be any reason that I know of so I was asking if anybody else had the same problem, or could duplicate the problem. I am really interested in using the OPPO's USB port for viewing movies, and since every one of mine (about 200) except these four work, I hoped to get some help.

What's the procedure to do a "hard reset" on this player?

(I chose "component" and now my signal is all scrambled)......

The recommendation for Zulu BD from England was spot-on! I just got it (Amazon.uk) and did a quick check... WOW! Only problem with the outstanding PQ is the blood looks like catsup

Look, as I said to proprog, no worries. I certainly hope for your dad recovers quickly and completely. That certainly is far more important than any trivial issues on this thread. And I am not looking for issues here. This is a wonderful thread and quite obviously you are a significant contributor. Keep in mind, however, that not everyone is an expert on all topics (that is, after all, part of what the forums are about, at least IMO), that this thread is hundreds of pages long and the FAQs is also quite long (and quite full of info). Again, not looking for issues and my best to your family.

The player has problems with 24p playback on some DVDs. Whether it is more the fault of the disc or of the player is unclear.

If it is not working correctly, turn off DVD 24p.

-Bill

Almost certainly video-based, therefore recorded at 30i. And that's how you should play it.

The short answer is that it's a Mac thing, and you're stuck with it unless you can delete the miscreant files using a PC. The Oppo's VIDEO_TS playback abilities are limited, though, so it may not do what you want anyway.

I suspect the deletion was because we're discussing rips, which is an AVS Forum no-no. Check your private messages.

Hi All,

I noticed some else had an issue with the "Enhanced Viewing" mode on HBO's True Blood Season One BRD--something about red and green being switched.

I have had a different issue--everything in the "Enhanced Viewing" works fine with the exception of the audio for the small picture-in-picture features that pop up, such as Lafayette's speeches and the faux-PSAs and commercials.

The video works fine, but there's no audio from the PIP boxes.

Anyone else have this problem or am I perhaps doing something wrong?

Thanks.

I have it off for now. I didn't test DVD movies yet but I will test that out later with the setting on/off as I was wathing Blu-Ray - Awesome!

I wonder if Oppo should implement an option to have an "Auto" besides of On of Off for the 24p on DVD.

Thine answer is in the faq.

Glad you're enjoying it. I don't usually spend much time listening to commentary tracks, but this BD has a really good one. If you're a Zuluphile, you'll surely enjoy it. I hadn't noticed the catsup problem, probably because I have the condiment filter enabled on the 83..

Probably too difficult. There's nothing on the DVD to tell it whether to be "on" or "off."

24p is part of the Blu-Ray standard, whereas DVD was always intended to output 30i. DVDs don't necessarily cooperate with 24p because that wasn't part of their mandate in the first place.

All this deinterlacing and 24p upconversion stuff is strictly an after-market thing, which is why it's so darn hard to find a player that can do it well.

Did you copy the entire directory over, or the files from the directory? I've seen file order change when copying a selection of files from a directory, but copying the directory itself preserves the order. Or at least it does on Windows.

That's sad. A real SACD player does bass management in DSD. For example, the SCD-XA9000ES does it correctly.

It sounds like Oppo wanted to sort-of support SACD, but converting to PCM mutilates the DSD stream. That is *not* the way to do it.

http://en.wikipedia.org/wiki/24p#24p_on_DVD

Doing bass management to a DSD signal is a very rare trick. The 9000ES you mention is not the only one, but it's one of the very few I have ever heard of. I don't know of any DVD-A/SACD players that have ever been able to offer that particular capability, and I don't know of any SACD players currently in production that offer it either. Of course, I could be overlooking a player somewhere out there...

A little update on what I found tonight...

It seems the subtitle not syncing with the frames definitely happens on DVDs (haven't retested BR movies), regardless of if it is set to 24p or not. It doesn't happen every time the subtitle appears/disappears (since there's some frames that will coincide with the end/beginning of the subtitle appearance), but it definitely happens.

I don't see any reason to believe its my setup causing this (seeing PS3 doesn't and I don't remember HD-A2 doing it), as subtitles should be part of the stream after it leaves the Oppo, so nothing should be able to change it (HDMI).

Am I really alone in noticing it, or do people just not use subtitles often?

Regardless, I suppose I'll wait for next firmware and hope Oppo team reads this thread.

Outside of this, I'm really loving my BD-83. It would be perfect machine if they fixed that, added 1.5x ff with audio support (like PS3 - I know, it's weird, but I used it occasionally), and a sleep timer.
