If you run VDR as root there is nothing to prevent VDR from filling up
/video (denial of service attack ;-) 

You could add some code to runvdr or whatever you use to start VDR to check
whether /video is actually a mount or not. A simple df shows you what's
there. If it's the root fs, ... you get the idea. A problem may arise if
you use the automounter to mount /video via NFS, and the mount fails for
some reason. Better mount hard,intr via /etc/fstab.
