greetings all,
i’ve hit a wall and i could use some help.
i’m working on a dynamic video player, and i’m trying to add a list component.
All content (video and titles) are loaded from an .xml
i have the video playing fine, and the titles are displayed in the list… so far so good.
My problemo:
i’m trying to get the correct video to display when the list is clicked.
i can get it to step forward but (i can’t get it to step back)
i’m lost… i’ve fould some video playlists online
but it seems everyone is built with the FlvPlayback component. mine is not
the only component is the list… i don’t even know if this maters…
any help would be grand…
