I also work in PAL broadcasting in germany, and the simplist way to be safe is anything you make in AE, put an adjustment layer on top with a levels effect set to 16-235 (black and white) and the gamma on 1.0. Like it was said above, the important thing is that your IRE doesnt go above 100. I check everything that goes out of my avid on a scope, and never have had a problem. And the people in the control room are quick to point out anything wrong, believe you me.
