Image Appears Scrambled On Select Warner Bros Blu-ray Discs

I have made a recent Windows 7 reinstallation on my PC and ever since then, a few select Warner Bros release BD discs do not play properly. The sound is jsut fine, but the image is scrambled in all shots that have a great aount of animation (lights, explosions, traffic, car chase, etc)

I have a AMD Phenom II 2 550 @ 3,10 Ghz
4.00 GB RAM
Windows 7 x64 (I need RAM for my job)
ASUS BR-04B2T BD Player
2x BenQ G2420HDB displays @ 1920x1080
NVidia Geforce 9600 GT 512 MB GDDR3

I tried updating the BD player firmware, tried playing discs in another software except PowerDVD, tried chaging the SATA connections, tried cleaning the discs, updating graphics drivers, disabled Aero before playback, NOTHING WORKS.

Below I attached an image of the issue and below that a video I made when watching a movie.

List of movies that present these issues: Batman Motion Picture Anthology (1989-1997), Batman Begins (2005), The Dark Knight (2008), Superman Returns (2006).

I recently watched Green Lantern (2011) and apparently the issue does not apply to that movie. Lord Of The Rings trilogy (released by WB via New Line CInema) also works like a charm. I REPEAT, this issue occurs ONLY ON BLU-RAY discs.

Below is supposed to be the scene in Batman Begins when Bruce faces his fear of bats in the soon to be Batcave, instead it's just...scrambled!

This is a video I made. Notice how the image looks at 00:45 and 01:25. If it would happen rarely I wouldn't make a fuss about it, but in The Dark Knight it even happens during dialog scenes if a shot occurs too quick. [URL] I stress to say this issue did not, in any way, occur when I first bought my Blu-ray ROM.
