I still don't know the answer, but let's explore something further:
 
1.       "Safe zones" as I understand them are not parameters within a video
file - aren't safe zones merely display-software calculated recommendations
pertaining to areas of a frame that those old NTSC TV's might crop? I don't
believe today's HD monitors behave that way, but might still be used for
protecting against display "letterbox" adjustments (just a wild guess).
Anyway I wouldn't expect anything in a video file to affect this.
2.       What is "resize" referring to? You say you are "resizing then
rendering" within PPro, but what are you resizing in PPro; what command is
this? Whatever it is, it possibly is not referring to anything within the
video file itself. Isn't a pixel ratio of 8:9 strange? Could it be some
software is attempting to adjust 8:9 to fit within a 4:3 display? Is 8:9 a
camera parameter??? Whatever, I doubt the answer is in the mpeg file.
 
Sorry - though it's interesting. Hopefully someone out there really knows .

Lee,
What I mean by "safe zones" is the borders that show where Action Safe and
Title Safe are. The original video specs are listed below, both for "not
resized" and "resized". The resized one was adjusted to be within the safe
zones in Premiere, and works perfectly when brought into Encore. I just
don't see any parameter difference in the resized and not resized files.
They were both rendered with exactly the same settings. It wouldn't matter
to me if it were only a few files, but I have to resize and render in
Premiere for fifty or more files! Any further ideas? I also tried to see if
there was a difference between Mpeg 2 and Mpeg 2-DVD, but there was no
difference in physical dimensions when importing to Encore. It is hard to
explain this, screen shots would work much better.
