Quadro K6000

My problem was outlined in an earlier post if you can search my post history. In a (big) nutshell, about 30% of the time when I pause playback my play head will be 1 frame ahead of where it is supposed to be -- then after a second or so it'll "hop" back one frame without my touching anything so that it's in the right place.

You can see the effect here:

Frame Hopping Back By 1 - YouTube

If you pause at 16 seconds and check the timecode above the smiley face (this is the timecode that the client burned into the media) you can see it is as 01:04:05:22. Then look at the timecode in the little box on the left of the timeline and you can see it is at 01:04:05:21. That's the one frame difference. Then press play again and at 18 seconds  you'll see the media "hop" back 1 frame so that it is at 01:04:05:21 - the same as the little box.

In the video, I am NOT scrubbing backwards one frame. I don't touch anything after pausing playback.

I didn't demonstrate this in the video, but I can often go back 2-3 seconds, hit play and pause the media at the same point and there will not be a frame difference. So this isn't my media being out of sync. I've had this problem for years across two machines. There is no rhyme or reason I can discern that causes this. Sometimes I can go 5 minutes without incident, sometimes every time I pause for 5 minutes there is an incident of this.

The film I am working on right now the media is an MP4. It's 317 MB. 1920x1080. 23.976.

To make the timeline, after importing I right click and choose "new sequence from clip"

I just updated Premiere Pro through CC this or last week - so it's the latest. In my ABOUT PREMIERE PRO tab it reads: "Version 12.0.1 (build 69)

I get sent my films as mp4 / h264. They vary in size, 250-400mb typically split.

I don't use effects. I just playback the media and pause when dialogue starts / stops / the frame a scene changes (so you can imagine why the hopping effect is driving me crazy)

I was looking into getting a Nvidea Quadro K6000, just trying to see if it is compatible with my mobo (ASUS Z170-A)
