Hmm, where to start.

1) Upgrading your system by changing your repo in your sources.list
file is generally thought to be a bad idea. If you want to upgrade to
a new distro release, use 'update-manager -c' instead.

2) The difference between 'upgrade' and 'dist-upgrade' is that
'upgrade' is only allowed to install upgrade packages that are already
installed while 'dist-upgrade' is allowed to install new packages or
remove packages based on new dependencies and/or conflicts. When
upgrading to a new major MythTV version, it is necessary to do the
'dist-upgrade' as the new libmyth package will need to be installed.
The Mythbuntu team generally recommends doing the upgrade via apt-get,
as it's easier to explain how to do the upgrade and also easier to see
if it's trying to remove any packages that it really shouldn't (for
instance if it's trying to remove half the system that probably
showing signs of an inconsistant repository)

Thanks,
