Problems with parenting an imported video

Hello, 

I have issues with parenting a Video.
I've imported a video and want to have it parented onto another layer so it does move exactly with another object.
Works great in stage view, but when I render it into an MP4, the video just stays at it's place and the parent object moves alone..
This really sucks, because I payed for animate and did not see that coming.
Can anyone help me here?

Thanks and regards, Torsten
