Problems with AD's version
we have problem with AD's version. AD that we put in front of some video, don't start immediately but
first you can see 1-2 second of video, then AD, then video again: http://mreza.tv/dnevnik-28-06-2014/

We manage AD's through DoubleClicks for Publishers. Can you advice us, what can be wrong?
AD's format and video formats: mpg4.
