Nvidia massive artifacts: hardware acceleration ROHQ with one series of 4K mkv
RD James:
1. Copy and paste the following command into a command prompt running "as admin" then restart Media Center if it is open.
--- Code: ---regsvr32 "C:\Users\<YOUR USERNAME>\AppData\Roaming\J River\Media Center 24\Plugins\lav64\LAVVideo.ax"
--- End code ---
2. Change Media Center's video settings to Custom rather than Red October/ROHQ and disable hardware decoding.
3. In the custom video mode settings, select your preference for RO/ROHQ, and add LAV Video Decoder.
4. In the LAV Video Decoder properties, select the D3D11 decoder and your GPU to enable D3D11 copy-back mode (copy-back is required for features like madVR's Zoom Control to work).

Wow. Thanks for the comprehensive step-by-step answer.
My gratitude to you, and jmone for his earlier help.
I found that the tsmuxed versions of the episodes had audio sync issues and video artifacts on seeking, making them nonviable for extended viewing. I will try the LAV registration solution. But doesn't that mean I have to register MadVR separately too?

You don't have to if you select ROHQ at the top of the custom video mode settings, rather than adding a video renderer to the list in addition to the LAV Video Decoder.

I would generally not recommend to use D3D11 as the default, because it still lacks a bunch of things. Most notably, you will not get any deinterlacing. Its also shown to not be fully stable with madVR quite yet (future madVR versions will hopefully improve on that), and its Copy-Back mode is more resource intensive then DXVA2-CB.
The issue with the sample in this thread is also already fixed in the latest development version of LAV Filters, so the next release will rectify it with default settings.

That's weird, deinterlacing seems to be working fine here. I use madVR's deinterlacing options though, so perhaps the reason it's working is because I'm using D3D11 copy-back.
I switched to D3D11 mode specifically because it seemed to be more stable with Media Center.
