Thank you Stephen,

I did the sudo su, and in the root home directory there already was a link
to config.xml  - must be done automagically because I don't recall
explicitly setting that. Anyway, I did the dpkg--reconfigure step while
root and this time it worked, however it wasn't what I expected, it brought
up the interface asking for root username and the root password, which I
entered, but is not the same as the mythtv username or password that's in
the config file. Then it asked if other machines were going to connect and
I entered 'yes' and that was it, after about 10 seconds it was done.

I took a look at the mysql error logs, and there's no entries from today,
and yesterday's log file was just a few messages about initializing being
successful and ready for connection, but no mention of any connection

Kinda a mystery to me, but either way MythTV seems to be working OK.
Although I do occasionally have failures relating to it not having enough
buffers when I change channels or enter into live TV. Anyway, I doubt
that's related to this.
