Cross post from the J.River Beta Forum as I "think" it is a madVR bug but...

1st Issue: madVR Windowed mode = Lip Sync issues on 23.776/24hz (the video is delayed so the sound come first)

There is no issue with:
- EVR
- madVR Exclusive mode
- madVR Windowed mode at 50hz or 60hz

I've tried different combinations and the following make no difference to the lipsync issues:
- Decoding Vs Bitstreaming
- Video Clock on or off
- Normalize vol on or off
- HW Accell on or off (eg CUVID vs FFDSHOW)
- madVR Settings of "delay playback start until render queue is full" on or off
- madVR Settings of "use a separate device for presentation"
- Pause/Play or a Seek makes no difference - it is consistently out
- Disabling auto refresh rate changes
- Manually pre changing refresh rates

My only conclusion at this stage is that it is madVR Windowed mode that delays the video when the refresh rate is at 23.976/24hz ...unless there is other suggestions on what to try.
