Hi: on my music files I used one song for the whole slide show and let it repeat itself.I don't think it was copy-protected but could be wrong. On the image file types all I know is that they were jpg's in My Pictures where I got them. I had 108 pictures in slide show with different transitions. About 20 or 25 of them I used the customized button. And in effects I had those same slides set for 3000. on the non-customized one's I left slides at 1500. I used the startup window with an image and had run, exit, on it. The music wasn't synchronized. the very first slide was set to display for 14 seconds and the rest set for six seconds. The first and last slide had sound added in. Had box checked for show navigation bar and also had allow to restore pictures checked. Music was set for all slides to play same song and to repeat. Had the screen set for full screen mode and all transition effects were checked. Also used my own text preference. Since this was my first slide show I didn't resize images or use different mp3 files or do any test shows because I wasn't aware you had to do all this. I more or less got pictures from album clicked add on pte and then clicked create, not knowing there was more to making a slideshow. And yes I was using 4.48. I hope this info will help and thankyou for helping out!!!
