It would appear you are doing everything correctly.
What is your initial FONT size?
So? “I typically render AVI DV widescreen, 23.976 w/pulldown. This particular video is not widescreen but all other settings are the same.” – Well, what is it? If it isn’t WS, then what is it?
When you right click on the SONY Text Properties what do you get under “Media”?
