Time Display problem

Hi

I imported a QuickTime video with a Time-code on it in order to do my film scoring assignment.
When I set timecode at cursor, the timecode in the transport panel get synced with the time-code in the QuickTime video.no problem…But…The problem I’m facing is when I select the time display, it is always four seconds ahead of the time-code in the transport panel and the QuickTime video…

any solution for this?
