IDVD Titles not Sharp

I hooked up my dvd player to my mini dv camcorder then fed that signal to Imovie '09 via firewire to capture the video from a slideshow I created 2 months ago. I made some changes in Imovie then shared it to IDVD and made a DVD. Now when I play it in my DVD player the text I put on the pictures in the slideshow in not sharp. I also have text only slides and they are also a little fuzzy. When I watch the original source DVD in the same player it looks sharp. How can I get the copy it to be sharp like the original disc?
