video transition

I have my Audioman Theme setup with a Video in the Header Media for my Homepage/Frontpage. This means when my homepage loads on a Computer the Header Image shows up first and then it transitions to the video url that I have specified. This is a really cool feature, however, many of my endusers say that the wishes the initial image would stay up for at least 5 to 10 seconds before transitioning. Does anyone know how I might could make that change. The site I am refering to is www.opovband.com. Thanks in Advance, Sam
