DV cameras all shoot at the same FPS (50-pal,60 NTSC) this as yet cannot be changed. You can adjust the shutter speed on DV cameras but htis has no bearing when getting slowmo shots apart from reducing any blur caused by motion.

When using editing software to slow your footage down it actually repeats frames to get the slo-mo look which is why it can appear jerky, the slower you make the footage the worse this is.

A way around this when using premier is to get a plug-in called Twixtor from Reelsmart or to use a compositing package like AE? or Combustion which will create tweened frames rather then just repeating frames which gives better results.
