yes, putting the actimeo=0 in fstab should work, that's how I do it.
I assume you remounted the filesystem after you changed the fstab file?

Each filesystem can have it's own settings, in fact if you remount a
subdirectory, you can have different settings within a filesystem. If
you have a shared nfs filesystem that has more than Myth recordings on it,
you can mount the filesystem the normal way and just remount the Myth
recorings directory with the actimeo=0 option, something like this:
(name of my fileserver changed to protect it's identity) :)
spike:/nfsdata /nfsdata nfs rsize=8192,wsize=8192,soft 0 0
spike:/nfsdata/myth /nfsdata/myth nfs rsize=8192,wsize=8192,soft,actimeo=0 0 0
That will leave caching enabled for the other parts of the filesystem and
only disable the attribute caching on the myth directory and below.

Just remount your video directory if it falls below the root mountpoint.

Running "mount" by itself will print out the current mount options for each
filesystem mounted.
