By using the fast forward function (2x, 4x, 8x, 16x, 32x) the video freezes or jumps back to the position 0:00
No chance to use the fast forward function.
Is there a solution for this problem?

Use the video skips, they will gradually take bigger steps when you hold that key.
Not much hardware can handle 8-32x video play speed anyway.
