Two .mov files- can extract valid gpx from one movie but not the other.

What you have posted is not a GPX file, but I think I get the point.  It is likely that the device samples the accelerometer at 10 times per second, and writes old GPS data at each of these measurements until a new GPS fix is obtained after 1 second.

Thanks for the reply.  You were right, what I posted was the output from the garmin app that reads the gpx file and plots track on a map.

I think your comment on what is happening makes a lot of sense, and explains the issue.

Thanks.
