getting video to autoplay in link from SharePoint doc library

Using SharePoint Server 2007, I've got a document library containing training
materials. From one of the training materials items, I want to link to a
video that resides in a SharePoint Video Library.

When clicked, the current link opens Windows Media Player but does not
autoplay the video; the screen is black and the user has to click the play
button. Is there a way to enable autoplay? Originally, the autoplay was set
to '0'. I changed it to '1' with no effect.

here is the URL:

..../Bamboo.VideoLibrary/Default.aspx?vid=1&vlib={378ACFD6-5DF6-414F-927D-C7A042B9F2E4}&autoplay=1
