Any ideas? Something is off with a codec I guess.
I'm following this discussion as well. How about DTS?

I started getting random video playback issues in the past few months. I am on JRiver 21, but haven't been able to pinpoint the problem. Seems like if I stop playback and then start it again, it works perfectly for the entire rest of the movie.

I too moved to Windows 10 a couple of months ago, but don't recall exactly when the video playback studdering (almost like a "bad buffering" issue) started, but it was within the last couple of months. I've tried power cycling all network hardware, restarting the server running JRiver, and the HTPC always gets shut down between uses. Made sure all Windows updates were there, etc. Seems like no matter what I try, it still does it.

Everything is uncompressed MKV across gigabit networking. My server and HTPC are quite powerful actually (overkill for what most people use). Playback is typically flawless for 10-20 minutes, then this happens, then I press stop on the remote (JRiver jumps back to the movie selection screen), and select "Watch" again. It picks up where it left off, and the whole rest of the movie will playback flawlessly.

Not saying that my issue is related, but this is something that started for me in the past couple of months, and it might correlate to the Windows 10 upgrade myself. I will try some Dolby and Dolby TrueHD tonight and see if I can get it to fail in similar ways...

I downloaded a Dolby True HD demo disk and every track that has the Dolby True HD logo in the bottom right is stuttery. Dolby Digital tracks, stereo, and everything else, DTS, and DTS-X work fine. It's only Dolby True HD that is broken. (audio is fine, video really jumpy, dropping frames, unwatchable)

My issue is on an overbuilt machine as well.

I should have provided this info originally but I'm on a
I7 -4770K
Fury X video card
16GB RAM

playing over HDMI bit streaming to a Denon AVR x7200WA.

Video is on Red October High Quality, (but it doesn't matter - ALLLLLLLL standard skips too)

To make it even more interesting - last night I figured out Windows Media player stutters on the same Dolby Digital True HD demo clips, as does VLC, as does Kodi.

So it's NOT just J-River. It's something else - and I have no idea what's doing it.

I created 8 mono impulse response filters in wav format using REW for my 7.1 setup on my HTPC. Does anyone know how to create text config file for JRiver convolution for multichannel? I've looked at the convolution links provided on the JRiver wiki. The only examples that I can find are for 2 channel, not 8, and I think if I could see a multichannel example, I could figure it out.

there is no difference to a mono or stereo file except the no of channels and the paths (filters) you define.

one example I wrote is republished on http://digitalroomcorrection.hk/http..._Workflow.html

there are some other examples on interact

if you're stuck then write down some logical paths (like apply filter channel 1 to L input and send to output 1) and I can give you some pointers on how to write it

I was struggling with the mapping of the channels for a 7.1 system. I think I figured it out. This is what my config file looks like now.

you appear to be routing your L input channel to each output via a different filter

Code:
C:\jriver\side right-filtersDIRAC80to500.wav  # filter file name
0         # filter channel so this means the 1st channel in the wav file
0.0      # input channel, 0 typically means the L channel
7.0      # output channel 8 (remember it is 0 indexed) which IIRC means SR in a 7.1 setup

So, is this correct? ( I added some paths for the same channel)

what is going on with the 2 separate filters for channels 4-6? I'm not sure whether jriver supports output channel summing, you should test this to make sure. It is also sending the same input channel to the same output channel twice, there's no scaling in the cfg file so I'd expect this to come out 6dB too loud (if jriver supports output channel summing).

The filter names suggest you're filtering a limited bandwidth in each filter, what are you actually doing in there?

For those channels, I did not eq the entire frequency range, only the problem areas. I was able to apply these wavs to the channel without any problems on EQAPO, and I thought I'd try the same with JRiver. It sounds fine, but I haven't had the chance to test with REW yet to see if I am getting the same results that I got with EQAPO. As for the scaling, it is not louder when used.
