Video playback goes well for a few seconds, then stops, but audio continues

Also, when the videos get done playing, the pictures afterwards look awful and blurry but not whe I stop the video and click on the pictures. Please help

Set playback to Full in the Program Monitor Panel.

When I start to play my videos they go well for the first few seconds then stop playing video but keep playing adio. Then within another second it does the opposite; playing video (blurry and choppy) but not audio.
