When I create thumbnails for chapter points with Spruceup, the thumbnails appear fine in author mode, but when I switch to test mode, the thumbnails are all shown as if someone placed a blue film over the pictures. The resulting burn looks the same. On one disc, I have two menus, and the first menu page looked as above, but the second menu page, the thumbnails appeared correctly. Anyone know what I am doing wrong? I am following the guide from this website.
