The pixel dimensions of a DVD frame are only 720 x 576. Therefore, displaying small text and detailed diagrams can be problematic. Use a resolution of 72dpi and keep your text point size above 16ppt. Text below 16ppt will be illegible.
Detailed stills, especially fine line drawings, are prone to flicker and to crawling pattern artefacts. If the detail of the still is important, consider producing a moving image which pans across the image. If it is important to view the entire image at once, be aware that the image may need to have a slight blur effect added, to stop the flicker.
Other detailed images that have caused problems are trees and water. Trees covered in leaves swaying in the wind and rippling bodies of water provide very detailed and constantly changing images. The only way to deal with these is again by softening the image. If these items are in the background then try and keep your background out of focus.
