StreetFire took the video down, so I could not see it. Sometimes that has happened when I download from the camera to the computer. Its usually that the computer program is dropping frames. I reboot the computor program and try again, which usually fixes the problem. If you took it somewhere, my first guess is that there is nothing wrong with your tape. Its more likely that the person who downloaded it did not watch the process and never realized frames were dropped. I would take it back and have them try again.
