The package manager will usually install the latest version by default.
You should be able to install a specific version using the format:

sudo apt-get install package_name=version_number

To make sure you have the 0.28 version available to the package manager
(PPA enabled and updated via apt-get update), you could:

apt-cache show mythtv | grep Version:

which should obviously show 0.28 and 0.29.

Finally, automatic upgrades will upgrade your system from 0.28 to 0.29.
You can stop this by placing the package in a hold state using dpkg.  The
dpkg command to do this reads from stdin, however.  Let's say you want to
hold the mythtv-backend package.  First type:

sudo dpkg --set-selections

then on the line below type:

mythtv-backend hold

then hit enter, followed by control-D, which should return you to the
command prompt.

You can verify the package hold states for all packages using:

dpkg --get-selections

or:

dpkg --get selections | grep mythtv-backend

to verify the hold state of the mythtv-backend package.
