Does YaST not have an RPM package for SuSE?  I thought that apt was strictly
a Debian or Debian-derived distribution tool.  If you installed myth from an
RPM, it should have cross-referenced the dependencies and told you which
version of MySQL was required.  Also, as far as I know, MySQL 5 is backwards
compatible with other MySQL versions (in terms of SQL language support,
anyway).

1.  Other than uninstalling the previous version of mythtv using apt-get,

I'd do a quick search using find or locate to see if there are any myth
files hanging around.  Delete any .myth dirs in home directories.  All other
files should be removed by your package manager as they typically aren't
touched by the user.


2. Is it OK to leave the mythtv user intact before I proceed? (I"ve read
> that RPM installs hang if user mythtv already exists)


Sure, why not?  If you have a user named 'mythtv', it's just a user.  An RPM
shouldn't depend on a certain user name... and if it does, it shouldn't hang
if that user already exists.  In fact, it should use the existing UID/GID.

3. Before starting, should I delete the mythconverg database somehow?

If you want a clean slate, then yes... I would recommend deleting the
database.  As for the command, first log into your mysql server (using the
'mysql' command).  Make sure you login as a user that has DROP privileges
for the mysqlconverg database.  Most MySQL servers typically have a root
user... use that one.  Then, the command is simple... immediately after
logging in, do a 'DROP DATABASE mythconverg' and you're done.


4.  Is there a way to purge the listings database?  Something seems wrong

The safest was is probably through mythtv-setup.  Run that and delete your
listing source by deleting and recreating your video sources.  This should
empty the entire program table from the database.  Alternatively, you can
try manually clearing the program table (I have no idea what this will do).
Use a SQL command like 'DELETE FROM mythconverg.program WHERE chanid>0'.

5.  My install of 0.19 had my channels off by one (I.e., the listings would

I don't have DirecTV, so I can't really speak to that.  As for having the
channels off by one, that happened to me once.  All I did was run
'mythtv-setup' again.  I deleted my listings using the method described
above and re-created it.  That fixed everything.
