To be more precise Marydb == mysql, why the package installer was not
satisfied with mysql is an error on the side of the package builder.

Some history.

At some time past some people did build the public domain database
system called mysql. As things go, they at sometime sold their product,
but then dissatisfaction with that selling to the commerce stepped in.
One of the original builders created MariaDB based on the original
source code, Maria if I am correct is the name of one of his
daughters. MariaDB tries to maintain compatibility with mysql and
mostly succeeds, but by now offers much more. While mysql still is
public domain, the public domain, more and more is choosing Mariadb.

However any software at present including MythTV can run with either.
A restriction to choose either is an ideological choice of the package
creator.
