I created a 40-minute slideshow with about 400 photos and 20 video files. I first created a regular DVD and it played perfectly on my system, but I have it to the person who is going to duplicate it, and there is no sound on their system. But that's the subject of the other question I posed 10 minutes ago.
I also burned a BluRay and I got no errors will building it, except that it complained about a photo having a duration less than 1 second. Sorry, but I need to have two photos alternately displayed for about .7 seconds each to synchronize with my soundtrack. The error message said that the navigation would be "incorrect." I just let it continue anyway.
When I play the BluRay it stops playing about 1/4 of the way through. The only thing I can figure out is that at the point the BluRay stops, there are two photos fading and another one starting (crossfade on track 1, and fade up on track 3). But why does the BluRay fail at 10 minutes, and the regular DVD works fine (except for the problem of no audio on some systems)?
