Wondering if anyone can help. Trying to do a slideshow with my denon 3910. It will play the first picture, but then will not play any more from the selected folder. You cant even manually advance the show, it just refuses to show any more pics. I dont know if this is a mac/pc thing. The disc was burnt on a mac (ISO 9660 format) and all the images were saved as jpg's on a mac. In the instructions is says it cant use jpg's created on macs, how come it can display the first image in the slide show? The same thing also happens on discs/jpg's created at a lab, which weren't done on a mac. I allways thought that jpg files were pretty universal opening on either pc or mac. If anyone can help, thanks.
