Any way to change pixel aspect ratio?

I have some uncompressed PAL sized (720x576 at 1.0926:1 ratio) renders that I have rendered from a 3d app. When I bring these into DVDA, it thinks that they should have a square pixel aspect ratio and therefore squeezes them vertically with black on the sides. Although when dragged onto the Vegas timeline(or preview) it correctly gives them a 1.0926:1 ratio. I know that I can render this file to DV or mpeg and DVDA will get it right. Just seems a bit strange that it gets it wrong on uncompressed files! Is there a way to change the Pixel aspect ratio on a file brought into DVDA...similar to the way you can right click a file in Vegas and change it via the properties menu?
Any help would be appreciated....
