Did you change anything else?  I've changed the permissions on my mythtv
database to allow me to connect from another computer and that didn't
make the backend lock up at all.  I've found that automatic commercial
detection will crash my backend without fail.  What version are you
running?  I had the commercial detection crash on both 0.16 and CVS.

I think the command you want is REVOKE instead of grant.

I compiled my MythTV from source so I haven't even got the backend to
run on boot.  Sorry I can't help with that...I'd like it to restart
automatically too.

I run it with 
mythbackend -l /var/log/mythbackend.log

Check a few lines back and see if anything besides a recording starting

Good Luck!
