This may not be what you're seeing, but I found that if cinelerra had to resample one or more of my audio tracks on-the-fly (because their sampling rates didn't match each other or match the project audio sampling rate), it took too much CPU time and caused "jerky" playback. Does your video play smooth if you turn off audio playback?
