DVD Encoding advice for mass distribution
I've found that not all DVD authoring programs, especially the low end consumer ones, don't always put out a truly compliant file to the DVD spec.
If you're on Windows, I really encourage you to encode using something like TMPGEnc using the default DVD settings with a bitrate between 5 and 6.5 mB/s.
Remember, no matter how hard you try, if you're writing to DVD-R/DVD+R there will always be set-top players that won't be able to read the disks. I've had better success with DVD-R. Check out vcdhelp.com for more info.
I use either Scenarist (at work) or ReelDVD (at home) and for those I always have the program make an ISO image and burn the image from the DVD burning program (RecordnowMax, in my case). This is in place of having the program burn the disk, for some reason I've had better compatibility this way... go figure.
Obviously (assuming you're North American) you'll need NTSC friendly compositions (720x480 / D1 pixel aspect ratio / 29.97 fps / lower field first). Slide shows can also use still images, depending on your authoring program, but they will always end up being 720x480 on the screen.
