CS3 Exporting/Resizing problem

Question

Hello
Although I have some basic experience I am not great with any of the Creative suite products. I usually will search and resolve any issues that I get but I could not find an answer to this one. 
I have been putting together a project in Adobe premiere CS3. All of the AVI clips in the project are exported from Adobe AE. A few of the AVI files were slightly the wrong size and so I adjusted them using the little handles in Premiere. In one circumstance I forgot to put an element into an AVI clip and so just put a PNG image ontop of the clip in Premiere. 
As I am nearing the end of the project I decided to trial exporting the piece, to my dismay almost every clip in the project has either resized or moved quite far from where it is actually placed in the project. In turn the PNG image is no where near where it was originally placed. While previewing the project every thing is fine, but after several exports it always ruins it. 
Any help would be greatly appreciated.
Tom

Most answers are coming from the newsgroup, where a bump
doesn't have
any effect except for adding more noise to the discussions.
It won't
push the thread back to the top, which is why it's considered
pointless
and annoying by almost every newsgroup regular.
And even in many web forums bumping is frowned upon,
especially if it's
done just a few hours after the initial post. In some
moderated forums
such frequent bumping may cause a deletion of the posting or
even a
temporary ban from the forum.
If you still think you have to do it, please wait at least 12
hours. But
as said - it's rather pointless.
