Bit of a newbie one this..

I've got a standard Ub 10.10 distro. + gnome. The file requester dialog doesn't give me an opportunity to type in a unc path or browse for shares. I can mount (?) shares with the Connect gadget, that opens up a File Browser window but how would I point, say, vlc to a network share?

(OK, VLC does have some tools for finding network shares but most apps. don't)
