Sound seems OK but video is mostly frozen or choppy

[JP Carsten]

Playing movie clips taken with Kodak PlaySport. downloaded with Shotwell and tried to play with Banshee. I can hear sound OK but the video appears to start and then stops- starts again stops and freezes.

Uploads to Utube directly from SD card to Apple computer work fine on Utube.
