MythTV from deb-multimedia setup?

[Jon N <jdnandroid@gmail.com>]

Hi,

I've built a new machine and installed 64bit Debian testing on it.  I
also installed MythTV from the deb-multimedia repository.  My old
computer has been used for MythTV (mostly recording/playback over the
air TV) for years, and I would like to have the new hardware take over
the job soon.  But I ran into a difference between the 2 computers I'm
not sure about.

On the old computer I can run 'mythtv-setup' when logged in as myself,
not the 'mythtv' user.  But on the new computer when I run it as
myself I get asked my country and language 1st, then on the next
screen, Database Configuration 1/2, I get the message "MythTV can not
connect to the Database.  Please verify you database settings below."
As far as I can tell they are correct. I can not get past the next
page (2/2), it sends me back to the country and language selection
again.

I did read the README.Debian file for MythTV and tried running 'sudo
-u mythtv mythtv-setup, but get the message "mythtv-setup: cannot
connect to X server :0.0".  To make matters perhaps a little more
troublesome there seems to be a little trouble with the new computer's
hostname so when I try the suggestion in README.Debian, 'xhost +local'
(as is, or substituting my hostname for 'local') i get a "...bad
hostname..." error message.

So, my main question is, other than just convenience how much
difference does it make to be able to run mythtv-setup as myself
rather that as user 'mythtv'?  Does it not being able for it to access
the database mean that if I run the frontend as myself it also won't
be able to access the database?

Thanks,
Jon
