Yeah, there's absolutely no need for routine/"scheduled" filesystem 
checks on a MythTV TV (or video or music or ...) filesystem.  Run it on 
your root filesystem (and other important-to-the-operation-of-the-system 
filesystems, but not on a pure data filesystem).

If you want, you can always manually run a filesystem check on the 
TV/video/music filesystem...  Simply unmount it then use the appropriate 
fsck /on your schedule/.  (After all, Myth is all about "on your schedule.")

Also, note that by specifying 0 in the /etc/fstab fsck-order, you're 
telling your system not to do an automatic fsck.  See "man fstab" under 
"The sixth field".  (This approach doesn't even require running tune2fs.)
