You are confusing the mysql user name to log into the database
(mythtv) and the system user who runs mythfrontend (mylogon).

This is how mythbuntu is set up.

I suggest you don't!! I don't know what will break in mythbuntu if you do so!

However you may have run into this bug, which I thought had been fixed
in later versions:

mythbuntu runs the backend as user mythtv and the frontend as the
user you create on installation (in my case 'nick'). When you set up
the grabber in mythtv-setup, it puts the config file in
/home/nick/.mythtv/Freeview.xmltv (where nick is the user and Freeview
is the video source name you allocated). The trouble is that the
backend running as mythtv does not look in nick's home directory, it
looks in its own, ending up with an error 512 (FAILED: xmltv returned
error code 512.) when mythfilldatabase is run.

I fixed it with a link, ie:

nick at media:~$ ls -l /home/mythtv/.mythtv/Freeview.xmltv
lrwxrwxrwx 1 mythtv root 33 2008-05-29 22:34
/home/mythtv/.mythtv/Freeview.xmltv ->
/home/nick/.mythtv/Freeview.xmltv


But as I say I thought this problem had been sorted a while ago.
