using ifoedit to change aspect ratio

[qpskfec]

I have used ifoedit to change the aspect ratio in a DVD with a single title ok.

Is it possible to use ifoedit to create a dvd that has 2 titles with different aspect ratios, one title that is 4:3 and one title that is 16:9?

For example, I have an authored DVD that has 2 titles, both are flagged as 4:3. One of the titles is incorrect and needs to be changed to 16:9 and the other title is correct at 4:3.

I want to end up with a dvd with 2 titles, one 16:9 and one 4:3.

When I open up the ifo file, I only see one place to change the video aspect ratio:

"Video: MPEG2 .......................... (4:3) ................"

Does this mean that when making an aspect ratio change using ifoedit, it applies globally to all titles in the dvd?

they have to be in different titlesets. each VTSxxx_xx.IFO contains a aspect ratio descriptor.
