You must have your tuners set up to be used continuously by MythTV. In
mythtv-setup, Capture Card Setup/Recording Options, you will have the
"Open DVB card on demand" option off for that tuner.  But I was under
the impression that with that option off, MythTV would not actually
tune the tuner until it first needed it for something, like a
recording or EIT grabbing.  So I would have thought that mhegepgsnoop
would not work until that first tuning happened.  If you have the next
option on that page, "Use DVB card for active EIT scan", also set,
then that would cause the tuner to be tuned immediately after
mythbackend starts.

You are right, root has a mysql password.  My database has been around
for a long time now - it has been upgraded with each new MythTV
version from 0.21 originally, before DVB-T existed in NZ.  So it
probably has all sorts of interesting things like that in it that are
slightly different from a brand new 0.25 database.  Since mysql is
accessible on my network, I think it is a really good idea to have a
password on the mysql root user.
