I'm having some trouble configuring the 2 together, what i'd like to do is have a "thumbnail" preview image of the video on my page, and when clicked, i want it to play the video in the lightbox as it's supposed to. i tried adding rel="lightvideo" to the embedded video code, but it won't play the video in it. i must be missing something, would anyone happen to know the proper configuration to get the two to work together? if flowplayer just isn't compatible, would anyone know of another flv player that can be used for commercial use that will work properly with it? any help would be greatly appreciated...
