I'm having trouble chapters on Sylvania and Sony players. I will hear audio, but no video when a chapter is clicked on. A potential client noticed a similar problem on her Sylvania. Oscar from MediaChance said it might have to do with frame indexing. I didn't read about it in the Quick Tutorial that came with my software and am quite upset it wasn't in there. I am having problems with Toshibas too. The DVDs I produce play back fine on Panasonic and Zenith DVD players. I understand there are many factors that could be causing the problem. I am using Fuji DVD-R (the format is not the issue). I am authoring using DVD-Lab 1.3.1 and burning DVDs using the latest version of Nero Express. Will frame indexing resolve my chapter problem? Thanks for any help. Tom H.
