I wondered about the Ken Burnes effect. I know that we should uncheck that box when we import.
It's perfectly okay to have the Ken Burns Effect checkbox ON when you import. No reason not to, unless you don't know yet what duration you want the slide to be and plan to adjust it later. Then importing with KB off will save a little time changing it later.
After it is in the clip viewer, can we put on the Ken Burnes effect without it affecting the image quality
I hope you haven't reversed something important here. Rendering an image to a video clip with the Ken Burns Effect is what you WANT KB to do. You don't want to avoid it. Turning on the Ken Burns checkbox causes KB to render the image while importing it, or when Updating it later.
On the other hand, you want to avoid iMovie HD ITSELF rendering the image later when you click the Create iDVD Project button. That can be avoided by previously rendering with the Ken Burns Effect.
Remember, when iMovie asks to render it may need to render OTHER types of clips too, not just imported images. It may be important to render those. That's why it's a good idea to render all your images with Ken Burns earlier. Then you can grant iMovie permission to render when it asks later without harming your images.
When it comes to doing its basic task, iDVD seems more profoundly buggy than iMovie, so it's hard to know what the problem might be. You asked earlier about exporting your iMovie HD project to QuickTime. Now is the time that might prove helpful. You may want to export the iMovie HD project to a Full Quality DV movie that you can simply drag into the iDVD project window. iDVD should be able to handle it easier.
But before you do, you may need to replace those poor-quality images with new copies. Once iMovie has rendered them the damage can't be undone. If iMovie has rendered the images and added jaggies they must be replaced with new imports where you've turned on the Ken Burns Effect.
I know all this is confusing -- bugs and workarounds often are. If you want to read more about it check out this long-running thread in the iMovie 4 forum, which predates iMovie HD. Most everything still applies.
