Hmm, I could have sworn this affected blu-ray via HDMI (I tried it with the AIX records sampler), but I'll have to try again to be sure.

It should only affect Digital Coaxial and Optical. HDMI uses EDID handshakes to determine what the bit rate and sampling rate should be, and is not a forced output.

After further testing, I think it's the preamp. The preamp's "direct" mode has the audio glitch, but it's "all stereo" mode (which allows for EQ, etc) was fine. I tried analog out from the Oppo and it was fine. There must be something wrong with the "direct" mode. Thanks all for your help!

Hi, On my Onkyo TX NR5008 in order to bi-amp my front speakers I have to lose my rear back surrounds and have wired them to front highs. My question is if I connect the '83 via multi-channel analogue will I only get 5.1, or will the amp route the sound to the appropriate speakers regardless. I don't really want to un-biamp my fronts as this kind of defeats the object of great analogue listening.

Bi-ampling will usually lose the Surround Back channels regardless of how you connect to the receiver as the receiver just does not have the power to bi-amp and run the Surround Back channels efficiently.

Biamping also usually isn't worthwhile with receivers because most receivers don't really have the reserves to drive all channels at the full rated output. So you essentially end up robbing power from one pair of channels to drive the biamp channels and vice versa.

Just an FYI though....in addition to biamping speakers, the 5008 does have the capability to "bridge" 2 speaker channels for one speaker...which provides a lot more than it's normal rated channel power for two speakers. I agree though that biamping with one receiver without external crossovers with typical speakers really isn't effective.

i originally had an 83, then sold it to get a 93 when they came out, mostly for the streaming cababilities. The remote slowness has always bothered me, plus the fact that it didn't have Amazon, so I picked up a Roku. Today I bought another 83 and it sure seems that the 2 channel audio(running into my 2 channel system) is a lot better than what the 93 was. Just wondering if my ears are messing with me. At any rate I'm glad to have the 83 back in my system, the remote works so much better.

Thanks for listening
Jeff

You always have to be careful when you listen to a different piece of equipment in your system that you don't confuse different with better. It may be better but it may only be different. Differences can draw us to hearing things we might have missed with another unit and we can sometimes equate that with better. I'm not saying that you didn't hear better sound, only that it is possible you were drawn by differences rather than improvement.

Started having some disc issues. LOTR would not play nor would The Matrix. They would start up then the LCD would go to 00:00:00 and lock the player. Discs played over my PS3. Am I needing an update or whats the deal here. Thanks.

Sounds like your 83 is having trouble reading the disc as opposed to any sort of firmware incompatibility.

Since the discs are playing in the PS3, the likely explanation is that the laser lens needs cleaning on your 83. If you are not comfortable doing that yourself, OPPO has fairly inexpensive flat rate service for players out of warranty.

Is cleaning the 83's lens something you would recommend after a few years of regular use, regardless if there's an apparent problem with it? Thanks. I know the method of doing it has been posted a few times, just gotta find it now.

Why I ask: I have only recently encountered my first disc the 83 wouldn't play that other players do. Not a firmware or disc-authoring issue, it's the 83 being picky. So I'm thinking I should help it out... [edit: I do think the disc is shoddily manufactured and it's being replaced, though "lesser" players handling it gives me pause]

I just sent my 83se in for a new loader as I have been having intermittent disk reading errors for a few months and I also wanted to get a replacement loader, while they are still available.
The tech evaluation from Oppo said that there was accumulated dust in the loader.
This may have been the cause of my read problems. I was surprised to read this as I just opened up my fan cooled DLP and found liltle dust after 2 years. Had I suspected dust accumulation in the oppo I would have removed the cover and cleaned it, which is what I probably should have done in the first place. Doh!
I did periodically use a lens cleaning disk.
So FWIW I would recommend pulling the cover off and inspecting for dust periodically, it could save on repairs and improve disk reads.
The cleaning procedure has been documented in this forum I believe.

Frequency of required laser cleaning is dependent on the environment. The only way to know if it needs cleaning is to open it and clean it. Problems with one disc is not really reason enough to do so. Sometimes a dirty laser assembly will cause problems first with one type of disc, either blu or red laser, but maybe not both.

^ Thanks. I opened it up this morning. Both lenses had that shiny glow that brand new lenses do...and I did a quick clean anyway. No difference with that one bad disc. Did a quick light lube of the rails for lenses and tray too, and the tray is a lot smoother now. The two large PS caps (68uF@450V) appear to have leaked. They test good for cap and ESR, but there is brown goo along part of the bottoms of them. Will replace soon, glad I opened it just for that at least, hate parts that don't look good and might be iffy.

Is the audio dropout issue with Brave (and apparently Pixar Shorts v2 and likely with Nemo) something that a firmware upgrade can fix...

...or is definitely an authoring fault at Disney and discs should be returned as defective?

Hard to say. The studios are the big dog here; if they want to push the authoring envelope then equipment manufacturers have to accommodate them.

A complication is: what if this is a capability interaction between the player and receiver? You might need firmware updates on both sides. That's a many-to-many fiasco.

If you want to be aggressive, return it as defective. Write the review sites and ask them to publicize. But there is no way to know if you will ever get a replacement disc with the problem corrected.

Also note that as far as I have heard, the problem only occurs when bitstreaming, Switching to LPCM is a practical solution if your receiver will take it.

It's authoring, although not a "fault" per se. the authoring issue is deliberate. Don't look for a firmware fix.

So long as they are just pushing the envelope, and not breaking the rules i guess.

I did send the Disney site a complaint and asked if they planned to fix it. I'm sure I'll just get a "standard" response.

That's what I've heard too - and probably what I'll end up doing (switching to LPCM).

Since it is only on bitstreaming, that would seem to indicate that the AVR's decoding capabilities are less than the players'. Because if a player can read, decode and send without issue, it can certainly read and send without issue.

I have watched Brave and Nemo a few times and have not had any dropouts. I have an 83 bitsreaming to an Onkyo SR707. I think it has a lot more to do with the AVRs than the players.

Do you have Secondary Audio ON? That would likely alter the problem.

The errors appear to arise from the file branching idiocy authored into Brave. That means they aren't going to show until near the end of the disc when played back starting from the beginning.

No, I do not have Secondary Audio on, never do. Bitstreamed in full 7,1 glory confirmed by the OSD of my player and AVR.

I received Nemo in the mail on Saturday 12/1 and Brave was a Redbox rental so I doubt if they were new or altered pressings. I'm not alone, there are other reports of members experiencing no dropouts with bitstreaming.

Issue: Audio
Player Make: Oppo

Details: I, like many other people, have experienced audio dropouts while watching the Brave Blu-ray. I have read reports that this also has happened with Pixar Shorts vol 2, and early reports indicate that the same issue is happening with Finding Nemo.

I have experienced myself with Brave and believe i will have to return the disc to Best Buy as defective. I would like to buy Pixar Shorts v2 but am concerned. I am afraid what i will experience when I receive my copy of Finding Nemo from Amazon in the coming days.

Due to the widespread nature of this issue it would seem to be an authoring problem there at Disney. Do you plan to fix these discs and do a recall?

The skinny is something like this: Dolby has several tiers to their encodings, and Brave, Finding Nemo, Total Recall, among others, are using the most recent tier. I'm going to call it "Dolby Digital 5" because I can't remember the technical name. The issue is that the platform that the BDP-8x of players use only support up to what I will call "Dolby Digital 4". The player's firmware will need to be upgraded to support "Dolby Digital 5". The kicker here is that due to the age of the decoder it is possible that the changes will not be made. MediaTek would need to be involved to enabled this newer Dolby Digital as this is a front-end decoder issue, and not a top level firmware issue.

That would make perfect sense it switching from bitstream to LPCM didn't appear to fix the issue...

...one would think the issue would be worse if the player was decoding instead of just bitstreaming...

...unless the glitch is so random (as it happens some plays and not other) that bitstream vs LPCM means nothing, and it has more to do with position of the moon and whether your dog just f@rted.

I'll do some more testing in the coming days and report back (bitstream vs lpcm, Brave, Nemo, etc - see if anything is repeatable).

You have to remember that any changes to the specifications also allows for compatibility with older standards. Just like how Dolby Digital TrueHD has a Dolby Digital Core for older digital equipment, "Dolby Digital 5" has information which allows older decoders to handle the audio. What becomes an issue is that the player can't send "Dolby Digital 5" as a Bit Stream because it is not being told to go legacy ("Dolby Digital 4") so it attempts to send a signal which is not compatible for. When the player is doing the decoding it knows to use the "Dolby Digital 4" decoding. This is why Bit Stream and LPCM have different results.

So in all reports I have seen switching to LPCM will resolve these errors. The errors only exist when the player is trying to Bit Stream the signal to your receiver.
