You export as 16x9.
Huge mistake...
Even 16:9 is in fact 720 x 576
What happens is that your QT has a 'display' set for 1024 x 576.
Now what you have to do:
either scale the QT's to 720 x 576 in QT pro and save (mind you, this is NOT a render, it's just the display you have to change!) or export again from avid with 4:3 set, just as 720 x 576
For the encoding you have to 'flag' the clips as being widescreen.
While i'm at it, watch out that Avid uses 'studio RGB', you have to tell Encore that or your blacks will be grey (not an Encore expert, do not even know if it is possible there)
