since a few days I have a problem with Blu-Ray playback with PowerDVD 12 on a Win7 system (with an AMD Radeon R9 200).
In dark scenes there's very annoying block building and a weird colors appear (for example in b&w movies it becomes purple)
Also, in lighter scenes there's sometimes a yellowish tint that shouldn't be there.
I didn't have this problem before and now it happens with all Blu-Ray discs I tested so far. And in another player (Leawo Blu-ray Player) I tested the discs, everything's fine.
What could I do to solve this?
Thanks in advance for your answer.
