it's flashing and looks like its showing left, right, left, right every other frame it still registers as a 3d disc but is unwatchable, I had this problem a few months ago and it suddenly stopped and all was well then it suddenly started again, i have removed clips, reinstalled numerous times upgraded and downgraded but it seems to still be happening for over a month now has anyone got any ideas please?
