Flv contentPath read from file server?

aloha, wasn’t sure which category to put this in really…

Problem: I have a flash swf file on a webserver, this flash file contains an flvplayback component, I need to play flv videos from inside the network domain using ‘contentPath’

[SIZE=2][COLOR=RoyalBlue]video.contentPath = “//server/dir1/mainVid.flv”;[/COLOR][/SIZE]

when I run the fla locally the flv loads in, but not when I publish the swf to a webserver.

Is there a seurity limitation here?
Any workaround
cheers
