There's a flicher when the first subtitle appears, using XySubFilter with MPC Video Renderer, and in DX11 mode, would it indicate a possible bug?

No flicker with DX9 mode.

Hi. I joined some old xvid avi's and wound up re-encoding the file to hevc stored in mkv using VideoReDo. I tried to play the file with MPC-BE 1.5.4 portable and nothing happens. MPC-BE starts, sits for a couple seconds and then closes. The video never starts. I couldn't find anywhere to turn on a logfile so I have no further details. I found MPC-HC has been updated by Clsid so I tried that (MPC-HC 1.9.0) and it plays fine. I also tested the file in Kodi and it plays there as well. Out of curiosity I remuxed with mkvmerge and then MPC-BE played it fine. So, it seems that MPC-BE might have a bug in its mkv parser?

Yes it is possible. But we do not know which versions of the components you are using.
In any case, I can advise you to change the "Swap effect" setting. If that doesn't work, then just use DX9 mode.

hi. so i have this problem back on MPC-HD (with madVR and lavfilters) where whenever i change subtitles or audio, i lost audio and video gets choppy (lower frame rate and frames missing).
after using MPC-BE with madVR and lavfilters, everything work fine for like 2 weeks, and then the same problem happen, didnt update anything. now way to recover from this, only restart player.
load ext subtitles works. i mostly play mkv files, and its the included audio and subs in the container that i cant change.
can someone please guide me as to what could be causing this? if you need any info just ask me. thanks.

Aleksoid, Volt, would you consider an option to allow a small rewind in seconds after resuming when paused?
My Yamaha receiver takes a second for the audio to re-engage so I have to skip back a step each time I unpause so I don't miss audio.
A user defined setting of 1-3 seconds or so could be useful, anyone else in a similar situation or also like this idea?

Use MPC Audio Renderer using Exclusive mode and release when idle ?

Yes, I've unticked release when idle now and it's better thanks. I would still make use of this feature if it was available though as there's still a small delay.

I tested latest MPCVideoRenderer-v0.4.0.1114_git2020.01.26-f040872 Nightly and if I enable D3D11 with MPC-BE and external LAV Filters I get a solid green video view. D3D9 is fine.
Going back to latest stable MPCVideoRenderer-v0.3.8.1060 solves the issue. I use Windows 10 Pro 64 bit with MPC-BE 1.5.5.5046 and latest LAVFilters-0.74.1-31 and AMD 20.1.3 driver for 5700XT.

I did some more tests, if I use DXVA2 it works, but if I use software decoding the issue appears. Same for internal filters of MPC-BE.

I got new DAC recently (RME ADI 2 on USB) and I tried it with MPC Audio Renderer, but the WASAPI exclusive mode is causing stuttering in movie playback. No problems in shared mode or with other audio renderer, but then the sample rate is obviously not auto switched. How is the WASAPI implemented in MPC? Push mode or event mode? For example in foobar this DAC has problems in event mode but push mode works OK. I also tried various settings in MPC Audio Renderer including buffer sizes but it always stutters in exclusive mode with any content no matter what.

Then I tried Sanear Audio Renderer from GitHub and it works without any problems in WASAPI exclusive mode with this DAC, including auto sample rate switching. No hiccups whatsoever. But I really would like to use the internal MPC Audio Renderer - can this be fixed? I am on win10 x64 1909, MPC x64 1.5.4.
