Heh - one more good reason to run daily backups of the db...
I've had db corruption twice in my 3+ years of using myth, and now my
backup script (run nightly) has the optimize script in it as well...
Usually I end up doing something really regrettable to the db when I
decide that I want to add another HD channel on my pcHDTV3000, then
realize that I've cooked the rest of them. Being able to restore
individual tables in those cases is *invaluable*... ;)
