iMovie / iDVD pixelation & noise

[Randy Clark]

Paula,
I've experienced the same poor quality still images on my recent 
videos.  I used stills from my Olympus C720 (shot at highest quality), 
and they appear very bitmapped on the resulting DVD I burned. Well, 
they appear very bitmapped EXCEPT during the transition phases from one 
clip (still, title or video) to another. during the transitions, they 
look perfectly normal.  This problem appears whether I'm watching it on 
a Mac, a 51-inch Toshiba projection TV, or a 36-inch Sony TV.  No one 
here has been able to adequately suggest a course of action or a 
possible cause for this issue.  I burned one DVD normally (i.e. 
creating an iDVD project straight from iMovie 4), and a second DVD by 
exporting the iMovie to a .dv file, then importing that file into iDVD 
and burning. I had the same amount of pixelation in both DVDs. Wish I 
could help more... I'm stuck commiserating with you.  I'm continuing to 
search for answers and will share anything constructive I find.
Randy
