Why is my video on adobe premier skipping frames?

I'm using a nikon d3100 (has full 1080 HD) & on premier i used the video setting "HDV 1080p30"
the video will play but it skips frames but it plays the whole audio?

Added (1). My video is about 23 fps… Any idea of what setting to chooose?

When you originally created the new file to edit the video in Premiere, did you make sure to change the setting to HD? If not, go to New and then file and then do this. Then import the HD video. Aside from that, it might be that the frame-rate of the video is not the same as that of the computer, or that your computer is simply not powerful enough to keep up with the HD video.
