Having just moved from Mandriva to Ubuntu, perhaps I can shed dome light 
on your difficulties, well, some of them, anyway.

(1) The Ubuntu (perhaps Debian?) install seems to create the 'mythtv' 
user in the mysql database with a generated password: mine was 
'ovrvzjvw'. All the on-line docs and examples indicate you should be 
running with 'mythtv' as a password. Perhaps the best bet is to use 
mysqladmin to change it back before going anywhere near mythtv setup.

(2) The 'mythtv' user, I believe, should be considered a 'system' 
account, that is, you should never have to log into a shell using it. 
Certainly up to now I have never found the need to. Your only link with 
it is via the various myth programs and scripts, which should all 
reference the mysql.txt file. Note there can be an alarming number of 
these files in different locations: why? Anyhow, do a find for them and 
make sure they all have identical values.

The only other time you might need the mythtv password is if you use 
mysql directly, that's fair enough.

Don't confuse mythtv as a system user with mythtv as a mysql user; the 
two are not equivalent, either can exist without the other.

(3) Ubuntu versions of the programs seem to want to change the names of 
the files - Mandriva=mythbackend; Ubuntu=mythtv-backend, for example.

(4) Possible problem with EIT data from the UK, if you turn it on for 
radio channels - some of them don't set the right categories for 
programs. I found every program for BBC Radio 7 flagged as a film - 
which makes browsing the film lists difficult.

Hope this adds some enlightenment for the shell-shocked, perhaps.
