Onkyo TX-NR818 "official" owner's thread discussion - Page 143

Thanks, these are great.

I would like to make something clear to avoid confusion. My test is a simulation of the issue and not a video capture of the 818's output. Although, that would be a good next step. I simply took the 23.976 test file and output at 24.000, as the 818 is reported to do. It's just to demonstrate what the bug looks like.

Oh, my mistake. I thought you ran it through both and captured the output, doh .

We'll I do believe that is the next step.

1. burn a test bluray disc at 23.976fps with the 23.976 test file.
2. play the disc back on a bluray player capable of 24p output.
3. capture the hdmi output of the 818's main out, at its output frequency (24.00 fps), with something like a Blackmagic Design Intensity Shuttle.
4. playback and step through the capture with frame by frame advance the video to see the actual issue.
5. pat yourself on the back and send to onkyo with definitive proof of a bug.

Hey Rich,

I had returned my 818 last week, as I was not going to play the waiting game for the 24p bug....

For some feedback, I have owned 4 Yamaha receivers over 20 years, and still own the last one I bought 8-9 years ago, the RX-V2095, and still works awesome today, I've never had one ever stop working, no hick-ups, nothing, they all have been perfect!!!
The 818 was my first receiver I ever bought that was not a Yamaha, so all I can say is I've always enjoyed the Yamaha's I've owned.

The only difference on brands is how picky you want to be with room calibration ( Yamaha is different than Audyssey )and over-all receiver features, and so on, as this was the only real reason many people here wanted the 818, for the MultEQ XT32 room correction and the many other extra's that come with it, which many in this thread have stated in night and day for the sound differences.

I did notice a BIG sound quality difference with my 2 sets of Klipsch tower speakers, and the center channel sounded much more clear and crisp and the depth of detail is second to none better, but there is 9 years time difference between the 2095 that's been powering them, until trying the 818, too bad the 24p bug, or I would have kept it, my Klipsch have never sounded so good!

I have. It's annoying.

Someone should post a HD YouTube video pointing out the 24p bug, so everyone popping in here will know in mere seconds what the 24p bug is and what it looks like.

When I enable 24p I notice a jerky, stuttery image that slows down every few seconds. Is this the problem? I am on an iPhone, so I can't view the file posted.

No.

I must have something else wrong then because when I toggle 24p on I get micro stuttering and the image appears to be slowing down every 30secs or so. I also see flickering. This only occurs with 24p. :/

Hi all, this is one for those in the know ! Just added front wides to my 818 Dali zensor 5 5.1 to make 7.1, whilst carrying out the calibration again I noticed that audyssey insists on setting the Dali 5's to 40 Hz and not full, and yes when I put them manually to full I loose most of the LFE to the sub. Point being what is the point of having large powerful speakers for left and right if they are never going to see any real bass ?

Am I missing something ? Cheers Simon

24P BUG RESOLVED ON MY 818:

well ok a little far fetched, but i was in the market for a new BRP so i got one with dual hdmi outs. problem solved...

What display do you have?

Sharp Aquos LC-60LE600U

It's unclear to me from the manual whether this display actually supports 5:5 24p@120Hz or if it's doing a 2:3 internally to 60Hz then doubling to 120Hz.

Do you see the same result if you bypass the AVR (plug the 24p source directly into the TV)?

This link to the excellent FAQ authored by the many guru's on the dedicated Audyssey thread should answers most of your questions. Specifically c)3.

http://www.avsforum.com/t/795421/official-audyssey-thread-faq-in-post-1/51750#user_C

I connected my BP to the TV directly with setting 1080p/24 and it ran perfectly fine. When I connected through the AVR and set 1080p/24 it look like it cut the frame rate to 12 as it was very choppy and very slow. It looked like a cheap old video card trying to run the lastest video game with max settings.

Do you have any true 24.000 content on hand or the means to play the 24.000 sample from this pattern set? It would be interesting to see what happens running that straight into the display.

Ok, it was my BP not retaining my saved settings. I re-seated the power cord on my BP, set 24p, double checked it and it runs at 24p without the slowdown through the AVR. Now I am just noticing only flickering on the images, and its more noticeable with text with 1080p/24 enabled through the AVR only.

I don't have a laptop to test those files out.

Update: it's the BP, causing my problems. It's not retaining the settings and it changes on its own randomly. I need to update the FW for my BP.

can anyone please help

Does anyone have experience using 818's preamp-out to drive an external amp? especially a professional amp which usually needs slightly higher input voltage? As I read the spec in 818 manual saying RCA pre-out rated only at 200mv/470ohm and maximum at 4.6v (vs rated at 1v/470ohm and maximum at 5.2v in 3010's manual). Seems like the pre-out in 818 is weaker than 3010. Not really quite understand those specs meaning. I just want to know from those who actually use it whether the 818's pre-out is strong enough to drive an external amp, and a pro amp in particular as I have a Crown xls2000 amp which is currently driven by a Denon receiver w/o problem. Thanks.

I'm curious as to why I can't seem to listen to any listening mode that ha audessey or DSX in it? Is there something I need to turn on in order to use some audessey setting listening modes? or DSX modes? All other listening modes seem to work. Im trying to switch modes on the fly with ORemote.

You need to have height or wide connected and choose that setup, I believed

the 809 is last years 818 right? what is the difference?

I had the 809 before my 818, apart from the lack of s-video and multichannel inputs, the 818 (to me) sounds much better. Having XT32 room correction certainly helps with that.

Ok thanks. I didn't realize that.

Regarding the 24p issue,

I am using a popcorn hour C-200 Network Media Player connected by HDMI to the Onkyo TX-NR818. The TX-NR818 outputs video through the main HDMI output to an Infocus SP8602 projector.

This setup is primarily used to stream 1080p/24fps (1080p/ 23.976fps) video from a server to the TX-NR818 and from there to the projector. I am still using the old firmware (1020-1100-0000-0000) which was factory-installed on the receiver. My projector has the ability to display the frequency of the incoming video signal.

My initial receiver setup was as follows:

A. On-screen menu (HOME)
1. Input/Output Assign
1.1. Monitor Out >Set resolution to SOURCE

B. Quick Setup
1. BD/DVD
1.3. Video
1.3.2. Picture Mode > Set picture mode to THROUGH

Using these settings and playing 1080p/ 23.976fps video, the projector detected a 1080p/24fps incoming video signal, exhibiting the micro stuttering artifact as previously described in this thread. The problem was evident both in actual video material and the test-pattern videos previously posted in this thread. This problem was quite pronounced and very annoying on a large front projection screen, so I contacted ONKYO Europe and complained about it. I was promptly contacted by a tech support rep who recommended the following settings:

A. On-screen menu (HOME)
1. Input/Output Assign
1.1. Monitor Out >Set resolution to SOURCE

B. Quick Setup
1. BD/DVD
1.3. Video
1.3.2. Picture Mode > Set picture mode to DIRECT

Setting the picture mode to DIRECT resolved the issue. Now the projector detects a 1080p/ 23.98fps incoming signal without any micro stuttering.

It would be very helpful if other people replicated these findings with other display devices, and more importantly with the new firmware.

I have the new FW installed and have made these changes...I will watch a movie tonight on my 125" screen and see if I notice the bug.

EDIT...Well this is interesting. I tried the movie I first saw the 24p bug on, The Best Exotic Marigold Hotel and started at chapter 27(?)...the second to last chapter with 10 minutes remaining in the movie and I couldn't see the bug. I used this scene because I could repeat the bug and it took my wife three times before she finally saw it the first time...it is gone but I am going to watch a proper movie tonight and will report back.

EDIT2...I watched a couple more demo scenes and a 2.5 hour movie and couldn't see the bug...I was really looking for it...at the very least these changes seem to "soften" the effect of a dropped/added frame.

For reference, I have an OPPO BDP-103 connected to the 818 and the main HDMI out on the 818 to a Panasonic 8000 PJ with no motion smoothing.

Hello to all.
I recieved yesterday my 818, ordered at amazon.de end of december and arrived home at Athens, Greece yesterday. In the meanwhile I was watching this thread and I was really concerned with this 24p issue as you have raised the issue really bold during my waiting period. I was almost in a depression situation. Well, I haven't yet connected my video gear to watch any film through my projector as I am doing some rennovation works, I hope next Saturday night to enjoy my first movie with the 818. But I do have connected my 2 fronts (Acoustic Zen Adagio) just to listen to some music, without any quick audyssey setup just out of the box, plugging in my cdplayer (Cd-120 Linear Consonance)....Coming from a sole stereo system with a Nuforce IA7-V2 I was really concerned jumping to the multichannel home cinema world that I would loose my musical nirvana (though limited due to time restrictions...well actually kids restrictions!!).
All I can say is that I am willing to bypass the 24p issue either by running the video signal through the sub main hdmi-out or even by connecting my PJ straight to the source bypassing the AVR. However settings posted from glk6655 I think are just enough.
818 seems to be the best solution to satisfy both worlds, stereo music listening and multichannel cinema sound. I am seeking forward to check what more I can get after proper audyssey acoustics setup.
Enjoy your systems!

i wish someone would make a youtube video of this 24p bug already, cuz i cant seem to notice it or find the issue myself and ive had a lot of friends over who are tech savy themselves and dont notice it either... this might be far fetched, but i wonder if its got something to do with the video processing of the avr and the type of display unit/ TV . You are using! cuz i cant seem to believe not one of my friends or myself cant find this issue... Someone please make a youtube video and post it, so i can get an idea of exactly what we need to look for

I've got a sneaking suspicion that somewhere in the last 3 months they have changed the setup/hardware slightly to eliminate the problem. But keeping hush about their fix.
