Hi Barry,
That "crazy" bit.
1. Was it making the camera's tape move backwards and forwards without defining a capture point?
2. Was it just moving back to a new start point?
3. Were your clips on the tape of a very short duration?
4. Did the camera/tape get fixated at one point and not move beyond it?
