Gap under video and above controls

Hi
We are using the video component and picking a skin “SkinUnderAll”. Everything is fine, expect that we get quite large gaps between the bottom of the video and the top of the controls - its really quite large on some examples. When we use Adobe Media Encoder to encode to flv there doesn’t appear to be any gap.

You can see the offending videos here http://www.en2krew.com/tutorialsmain.html

Can anybody suggest where the gaps are coming from and how to get rid of them

Thanks
