Video scrubber problem

[this is a repost, but I’m adding additional information.]

I’ve created a custom video player with a scrubber that follows the video progress and that you can drag (scrub) to go to a different position on the video.

THE PROBLEM: When I scrub the video and then release, the scrubber jumps to some position to the right of where I release it, rather than just proceeding from the point of release.

The code that pegs the scrubber to the video, or the video to the scrubber during scrubbing, is in a function fired by a timer. That function also populates a dynamic text field showing the scrubber position.

function updateVideoScrub(e:TimerEvent):void {
	if (scrubbing) {
		ns.seek(scrubber.x * vidDuration / progBar.width);
		progLabel.text = (scrubber.x * vidDuration / progBar.width).toFixed(2);
	} else {
		scrubber.x = ns.time * progBar.width / vidDuration;
		progLabel.text = (scrubber.x * vidDuration / progBar.width).toFixed(2);
	}
}

Elsewhere, a MOUSE_UP function updates a streamLabel TextField whenever the scrubber is released:

function mouseUpHandler(e:Event):void {
	if (scrubbing) {
		scrubbing = false;
		streamLabel.text = ns.time.toFixed(2);
	}
}

Looking at the progLabel and streamLabel TextFields, I see that regardless of where I release the scrubber, the video resumes at x.02 seconds, where x is the nearest even number GREATER THAN the point where I released the scrubber.

So, if I scrub to 10 sec. and release, the video starts at 10.02 sec. If I scrub to 10.3 sec., the video starts at 12.02 sec. If I scrub to 11 seconds, the video starts at 12.02 sec. If I scrub to 12.03 sec., the video starts at 14.02 sec. Etc.

Why does this happen?

FYI, the video I’m using is an 18.7 sec duration FLV file that I created using Adobe AfterEffects. This was the first time I have ever used AfterEffects and I’m wondering if my problem has something to do with cue points or something similar. I did not set any cue points but I wonder if there is some default in AfterEffects that sets them??

BTW, this also appears to happen using an FLVPlayback component to play the same video.
