How does bit rate effect video and slide quality?

[johnharlin]

I just made a DVD of a slideshow in the top three levels of quality given which were best with bit rate about 9,000, good with bit rate about 6000 and standard with bit rate of about 4000. I could not believe that bit rate would effect slides but it does. In the standard level, some of the slides flicker. In the good level there are little dots in the image that flicker and in the best there is no flickering. I cannot understand how the bit rate could effect nonmoving slides.

There shouldn't be much difference in a slideshow with no transitions/panning with those bitrates. What software are you suing? Maybe it's doing something else different. Post samples.
