I suspect you are suffering from what is commonly known as 'The Jaggies'. This comes from iMovie rendering your images as video. There are a few work arounds to avoid this, but they are very time consuming. I suggest you make your slideshow in iPhoto and export to Quicktime and import to iMovie for titles and audio, then use this file for your iDVD project.
If you want more info on work arounds for the Jaggies search the iMovie forums for hundreds of posts relating to this problem. Pay particular attention to posts by Karl Peterson. He is the man with all the tricks and know-how for iMovie.
I hope this helps.

Currently Being ModeratedOct 8, 2006 8:20 AM (in response to suzannenz)Sounds like what you are seeing is an interlacing effect. TV sets take 2 images called Fields that contain every other scan line (one has the 'even' lines, the other the 'odd' lines) and alternate the two Fields to make a complete video Frame with all the scan lines - NTSC alternates at 30 times a second and PAL alternates at 25 times a second.
With a sharp still image, the 2 Frames are slightly different. This switching back and forth between the 2 slightly different images causes the flicker.
One way to eliminate this is to use something like Photoshop to de-interlace the images (Filter>Video>De-Interlace). This will make the even and odd Fields the same so there will be no flicker.
After de-interlacing the images won't be as sharp on your computer monitor, but they won't flicker.
