Embedded Videos in Adobe Acrobat X Pro

Question

Hi
When viewing an interactive pdf I have created with embedded .flv files in Adobe Acrobat X Pro, there is a grey box (the size of the video) that quickly flashes before the file is played. I have set the video activation settings to enable when "The page containing the content is opened". Every time I open a page with video, the grey box appears before the video plays.
Is there a way to not have the grey box appear before the video plays? Or is there even a way to edit the color of this box so it is a less noticeable transition in my documet? I assume this is some sort of default setting to be displayed when the video loads.
Any suggestions regarding this issue would be greatly appreciated.

Video in PDF is stored in a compressed format (flate), which has to be uncompressed at the point the annotation is activated. Depending on the video and the system specs of the viewer this can take a second or two, during which time the playback widget has nothing to show. You'll tend to see either a blank space, or the default color of the Flash stage.
With the Multimedia>Video tool you can't change the stage color, but if you manually add the video widget and resources using the Multimedia>SWF tool there's an option to make it transparent.
