Please help Pixel Aspect Ratio

Hi people,

Going completely up the wall here, can someone possibly give me a solution.

Basically:

1) I create an avi in After Effects CS4 with preset: PAL D1/DV Widescreen (720 x 576). Pixel Aspect Ratio (D1/DV PAL Widescreen 1.46)


2) Then I save the last frame for use as a menu in encore (composition > Save Frame As > Photshop Layers)


3) Import the Avi into Encore : Import AS > Timeline, then import the menu: Import AS > Menu.


4) When I preview the project, the avi plays fine but when it switches over to the menu, the menu seems to squeeze vertically producing slight black bands at the top and bottom of the screen giving the obvious effect that the menu is not part of the avi.


Why oh why, no matter what I do can I not get the menu to display at the same size as the avi, have even created menus in photoshop CS4 with the correct PAL and PAR settigns but still the same result.


Please see the image below: as you see when the avi jumps to the menu which is really an export of the last frame of the avi, encore seems to compress it vertically:
