This points to where you question the Home Slideshow maker if they know how to accommodate the PS3. It sounds to me like a choice of audio encoding but as you only supplied Home Slideshow and no details I can't write anything more specific.
I Burned a Home Slideshow to a Sony DVD-R disk. When I tried to play it back in my PS3 the Video was OK but the Audio was distorted and Volume varied up and down.
The DVD output volume plays fine on my Computer and my PS2. The PS3 is connected to a Mitsubishi 52 inch TV via HDML cable, all games play fine and there is know problem with Game Audio.
Any ideas why I am having this problem?
Thanks for any help.
