Bad looking text in Encore CS4 DVD

Hi,

I have created a DVD of still photos in a video in Encore CS4. Introductory and ending text was created in After Effects CS4. Once DVD is burned and played back the text is not crisp and has some jagged edges. I used a True Type Wedding font called English (medium)(free font download) which is a somewhat thin font. Font looks good in AE and in Premier (when monitor set to 100%) but not too good once burned to DVD.

Am I doing something wrong or must I simply use a broader font?

Thanks for any suggestions or help.

George
