Denon DVD3800BDCI Owner's Thread - Page 148

Well more bad news - my service center says it is not the laser assembly so sounds like they replaced it with the still the same issue with powering itself down. Now they say they must replace on the main circuit boards and have to wait till next week for the part!

wow, that's too bad. That's why it's best to [only] deal with the main Denon customer service at their Mahwah New Jersey headquarters, they have all the expertise, parts, experience and more (elaborate test equipment/facilities). They can better assess the situation.

Yes I should have done that. My dealer knew the repair service center but like you said, Denon is more well-equipped to find the problem and repair it the first time. I now wonder if they will just keep the laser assembly on (the new one) since there have been failures from the initial batch. I don't want to have to go through another service if the laser fails after this is repaired.

yeah-I am keeping my fingers crossed too! thanks

I may have asked this before but what is most optimum selection for HDMI Select- YCbCr or RGB? I'm using a Pioneer Kuro (8G) display.

okay, I finally broke down, burned the latest firmware (v1.115) onto a CD-R, and installed successfully. Quite a process. Nero can be a little confusing trying to configure (ISO, etc.,...), but I managed to get things working properly.

Had to reset my DVD-3800BDCI set-up/configuration. Things seem to operate very well.

I watched the BD title "Burn After Reading", very good film. Player performance is excellent. Noticed I'm getting "DTS-HDMSTR" in display now.

Also was able to successfully set the DVD-3800BDCI remote to "DENON2", so it does'nt conflict with DVD-3930CI remote (instructions on page 6 of DVD-3900BDCI manual).

Now I've gotta play around with the latest firmware for my Pioneer BDP-05FD so I can do some comparisons.

Hi Kal:

Just wondering, the DVD-3800BDCI Down Sampling settings are explained as such (from the manual, page 33)- ie.

"ON": LPCM signals are converted to 48kHz for output.
Set to ON when using digital connections to an AV amplifier that is not compatible with sampling frequencies of 96kHz.

"OFF": For BD or DVD recorded in LPCM without copyright protection, 2-channel audio signals of up to 192kHz are output as LPCM signals with no conversion.

I have my unit set "ON", I'm using HDMI (via-LPCM) going to a NAD T175 surround processor. I'm not sure if my Halo A51 amp is compatible over 48kHz? (I listed the amp specs below)


Continuous power output:
250 watts RMS x 5, 20 Hz - 20 kHz, 8 Ω, all channels driven
400 watts RMS x 5, 20 Hz - 20 kHz, 4 Ω, all channels driven

Current capacity:
60 amperes peak per channel

Power bandwidth:
5 Hz - 100 kHz, +0/-3 dB at 1 watt


Would "ON" be the proper way to go here? Appreciate your help.

you are confusing frequency response with sampling frequency. 192khz is the sampling frequency rate that the digital stream is being outputed. 5-100khz is the frequency range that your amplifier is able to process (ie, 5-80hz is LFE, etc).

your amp has nothing whatsover to do with sampling rates, so you are fine.

However, I would bet that if he had sent it to Denon, he would not have had any chance of a new laser assembly; they would have repaired what was wrong, and that would be it.

At least now, there is a possibility of keeping the new laser assembly. Otherwise, the original one might fail after your warranty expires.

Select YCbCR.

Tried this last night. The combined R and L channels are muted when there is a multichannel output.

Regarding the analog outputs. Assuming a 4.0 channel system, 4 full range speakers with no center channel, no sub and no back surround channels, is there any down side to using the dedicated R and L outputs for the front channel speakers and the surround R and surround L for the surround channels?

I have always been a little confused on the downsampling instructions in the manual. Since my Arcam avr300 is compatible with sampling frequencies of 96Khz (I beleive), I would have thought that off would be the appropriate choice?

maybe you're right. But the factory may have recognized it's serial No. as one of the original production lot and may have replaced the laser anyway? Who knows?

I know. I'm concerned that my components (amp in-particular) may not properly handle that rate?


yeah, that's why I posted that spec., did'nt mean to confuse you. The power bandwidth (5 Hz - 100 kHz) is what I was concerned about. I assumed that the "ON" setting would limit sampling rate to 48kHz (within the amp's 100kHz threshold). And that "OFF" would allow sampling rates beyond 100kHz to be processed by the amp potentially damaging it?


I'm not 100% sure about this? Thanks for your input.........

MORE GOOD NEWS FOR 3800 OWNERS...

The 3800 decodes DD+. This is really not a big deal in terms of content but the player does do it (decodes to 7.1 LPCM).

I had a Blu Ray test disc I forgot about from Dolby received at CEDIA. It has a DD+ sound check area where it will send individual sounds to each of your 7.1 speakers. IT has a DD+ demo clip as well.

Sure enough, played the DD+ track and a 'DD+' light appears on the Denon!!

yeah, this is very confusing. Even the Denon tech's and engineer's are confused which way to set this (I called New Jersey a few times about this).

I hope they keep the new one it too. I called my dealer to ask them to keep the new assembly in and also do the factory firmware update (they have the ability) as well so I don't have anymore issues with it.

Ditto - that is what I also use

If they don't, nothing will be damaged and you will simply get no sound. Not a concern.


Again, the sampling rates (48kHz or higher) have nothing to do with the frequency response ratings of the amp's power bandwidth. Nothing!


Apparently. The sampling rates have only to do with the digital input of the processor or AVR. They will either play or they won't and you will know right away.

I see, thanks for confirming this Kal. So there's no problem on the processor-side as well? It will either process the signal or not (not damage)?

Yes.

Popped in this BD last night and it plays thru 2 previews and then screen goes black! After about 2 min the player displays "Stop". It appears when it supposed to load the Java (and displays some sort of loading icon) is where it is failing.

I'm running an earlier 3800 (Already replaced failed laser assy) with 1.115 Can someone else confirm this issue? I fear it's another FW problem as it behaves exactly the same after 3 different attempts.

Hi RBFC:
Is there some experimentation that has left people with the impression that AL24 processing is only applied to the 2 channel outputs or just some, IMHO, misinterpretation by folks of the block diagram?

Look at the "Advanced AL24 Processing" section, on page 2 in the manual. Sorry, I can't seem to copy it here. It makes me think that it works for both sets of outputs... They call the multi-channel support "AL24 Processing Plus".

I must admit that I woud be very interested to hear your opinions of the differences between the two sets of outputs. I read someone's post a while ago that the circuitry for the 2 channel is supposed to be better than for the multi channel. Not sure if that is true or not.

Cheers

HEY Bland,

Is it possible for you to take a picture of the display?

DVD Man:
Can you explain why? I read somewhere in the Kuro posts that YCbCR uses only partial bandwidth whereas RGB uses full bandwidth signals. I have no idea if that is meaningful or not but I am trying to understand what the differences are.

Also I have read that MPEG4 is a YCbCR based system. Doesn't a plasma or LCD ultimately need be the signal to be RGB to show it on screen? Isn't this really a question of which component you want to do the processing?

I have my 3800BDCI set to RGB Enhanced (0-246) so that the player will do whatever is needed to feed RGB into the TV (a Kuro Elite). I also have the Kuro set up to receive the (0-255) RGB signal (HDMI Color-4). What is wrong with that approach?

JDMI: What do you use? You have this same combination, don't you?

Cheers

Richard

OK, last night, I pop in 'The Dark Knight.' As it is a WB release, I go into the disc set-up menu, and select TRU-HD. I leave the room for a minute, and my girlfriend says 'Hey, the sound is out of sync!" Wow, it must be REALLY bad (I'm thinking) for HER to notice. Sure enough, it is very badly out. So I restart the disc, and it's still bad. Hmmmmm.....then I restart again, and let the WB Disc default to DD Multi Channel. Voila! Perfect sync.

Try as I might, I could NOT get the damn disc to sync via TRU HD. The thing that really bugs me, is that all my other discs have played perfectly in TruHD, and the sync was perfect in TruHD and DD. I'm running analog outs for the loseless codecs, into a Theta 6Shooter. I also run a Digital bitstream into my Theta for standard lossy codecs if I choose to go THAT way. The 'Dark Knight' BD was out of sync when TRU-HD was selected (via analog out), and in perfect sync when DD was selected (via analog out, AND via the digital bitstream....)
The Denon is set up:

BD Audio Mode-HD AUDIO OUTPUT
HDMI AUDIO OUT - AUDIO MUTE
7.1 AUDIO OUT - MULTI CHANNEL
SOURCE DIR; OFF

WHY WOULD ever other BD played in TruHD be in perfect sync, and THIS one not????
