I have recently been using my Sony DRX-830 UL to burn a photo slideshow(dvd). Before buring the preview on the pc has perfect picture quality and perfect sound quality. However after I burn and play it on my dvd player for some reason there are certain parts wherein the sound would scramble. Each time I burn at a different section of the slide show. I don't know what the problem is. I am using Dvd-R discs. My player is Union but the same thing happens when i play it in a different player. Please help what do i do to remedy this problem? I have wasted over 10 dvd-rs trying to remedy it. I am currently using Nero 7.1. Thank you.
