No Flickering at all anymore.
I didn't see it in the Preview, and it isn't in the Created Disc Files. It does not matter if 1080 60p or 60i. The Video is great.
And my Video with many Effects and Titles doesn't Flicker Anymore, too.

I'm uploading. But my upload isn't very fast

Here's my DXDIAG. If it should help.
I think, it's not a codec issue, because ALL of my Clips from different Cameras has this issue with PD13 with GTX970.
