I just read that "the dvd-region is also kept in PRAM. If the PRAM is being reset, than you can't change the dvd-region". The dvd-region will be reset to fabrics defaults - that might be not my region.

So if I'm doing what you suggest than my first problem might be fixed but suppose the dvd-region is changed then I'll have to deal with a larger problem which is not being able to watch dvd's.

What does Apple mean by fabric -defaults? Is it the settings just as I received it when I bought my system?

no, it won't. this is completely wrong. resetting PRAM will have zero effect on the DVD region set for your DVD drive.

Reset the resolution in Display Preferences.

Choose a different resolution and set that. Then go back to your original resolution and set that one. Restart.

Thanks for the advise. I was about to follow your instructions. Then came along another advise which seems to be less risky. That solved the problem
However, I'm thankful for your effort in trying to help me. And I'll remember that the dvd-region setting will remain after a reset.
Thanks again

glad you fixed it but FYI resetting PRAM is NOT a risky operation. it's quite on par with just turning the computer off/on. it's an absolutely standard troubleshooting procedure which carries zero risk.
