 Sure.

 You did chroot before trying that command, right? Does a vgdisplay 
show your volume group okay (ie: did your rh9 rescue disk handle 
the vg)?

 e2fsadm does logical volume and ext[23] filesystem resizing all at 
once, btw, so I prefer to use it.

 You could shrink the logical volume for / (since you haven't
extended the fs, if you shrink the lv back to what it was, the
process will be non-destructive), extend the /var lv,
mv the media dir to /var (eg: mv /video /var/), and then symlink
the old media dir (eg: ln -s /var/video /video).
