I created a DVD using DVDSP with one main menu and 2 title screens. I've burned a DVD straight from DVDSP, and done a build and burned out of Toast. The DVDs work on everything (pc, pc laptop, imac G5, G3 tower, G5 tower, dvd player, mac book pro)- EXCEPT an ibook. When I play it on the ibook it works, but my title background and menu background does not show up. Has anyone ever experienced this before?? Advice?
