Field Dominance issues with sequences

By default my sequences are set to a field dominance of lower field first. When I make a title in FCP or import a still and resize it I get a lot of shakyness and jagged edges with this setting. If I change the dominance to none the problem is fixed, but both lower and upper fields give me a problem. What is the reason for this? Is there a way to get these images to look good while using fields or just change a setting to make both interlace footage and non interlaced titles and stills to look good?

What version FCP you using?

FCP 5 HD. What I'm wondering is if the field dominance only effects final cut generated material and if you bring a field rendered object from After effects if it will still see the fields? Is that what this option does?

I am having the same problem with Animation QuickTime GFX. Also using FCP 5. FCP is convrting my GFX...
