fps drop in mp4 video

hello. while playing a mp4 video file which is 23.976 fps with mpc-hc the fps keeps changing between 16 and 24 but windows media player runs at 60 fps and ffplay at constant 24 fps. i tried different renderers like evr, vmr9, vmr7 and old video renderer and disabling hardware acceleration but the stuttering won't go away. need help with this please

I need a link to that video. I can't help just based on that description.

oh sorry i forgot to send the file. here's the first 10 seconds of the video file

The file has bad timestamps that give this behavior.

With EVR-CP as renderer, use this:
Menu > View > Renderer Settings > Presentation > Enable frame time correction

it worked. thank you for help
