Yep, I specifically checked the codec box just to make sure. The codec issue had been raised earlier, but so far tweaking doesn't seem to affect them. But I wonder if there's anyway I can disable the main screen loop video and neutralize it for good, so I can check for sure if this problem isn't codec-related...
Video drivers are up to date too, and I tried several ones with no luck.
But thanks anyway, your recovering gave me some little hope

Im sure I must have some problem related to yours, I just have to find the right thing to disable so I can have some happy
kaleun time again
