[flexcoders] Does setting PlayheadupdateInterval time affect videoEvents?

[luvfotography]

For the VideoDisplay, 
does setting the 
playheadUpdateInterval="500"

cause any bad effects?

When a video finishes, sometimes I'm not getting the
VideoEvent.COMPLETE event.
I have:
myPlayer.addEventListener( VideoEvent.COMPLETE, flexPlayerComplete);

Could this be because the interval is too slow??? and misses it?

Instead, I'm getting a seek event and the video repeats itself, and
then I get the Complete event???

thanks,
