Mplayer and FLV files in Fedora 13

Hi, It appears mplayer cannot handle play FLV files correctly in Fedora 13. I get no video at all. Totem works fine. Is this a known issue? Also gnome-mplayer always throws out the error "Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory" every single time in a dialog box even though my system has a Intel display.
