Screen flicker on movie

[g12345567]

I just started watching The Driver (1978) on blu-ray. Whilst the movie plays fine I noticed some screen flickering throughout. This is the first movie i have played that does this. So not sure if the problem is with my setup or the blu-ray itself.

I tried some of the screen settings I in the blu-ray player setup. As outlined in this thread but that didn't help much as all.

Screen Settings > YCbCr/RGB (HDMI)
Set the colour space conversion for the video signak from HDMI

AUTO
YCbCr (4:2:2)
YCbCr (4:4:4)
RGB

Just wondring if anybody else had come across this problem when playing blu-rays. If so what would be the likely cause of this and how to fix.
