I don't have an R600 based Radeon nor do I use aticonfig, but could you
check your /etc/X11/xorg.conf Device section for something like this:
Section "Device"
        Identifier      "ATI Technologies Inc Radeon R600-based card"
        Driver          "fglrx"
        Busid           "PCI:1:5:0"
        Option          "VideoOverlay"  "on"    # <--- This line needs
to be here for Xvideo to work

I use an R300 card (Xpress 200M)... I am not 100% certain that newer
cards such as those R600-based need this line but I would think it would
be the same for anything using the fglrx driver.
