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.)
