There are ways. That's how I do here.

First make sure the binaries are installed in two different paths.
that means you can't use 0.27 and 0.28 binary packages  you'll have to
compile one yourself

Eg. ./configure --prefix=/something/that/is/different/to/the/other/install

then make / make install

The easiest then is to use a different user to run it so you have no
conflicting mythtv config:
to run it:
LD_LIBRARY_PATH=/something/that/is/different/to/the/other/install/lib
/something/that/is/different/to/the/other/install/mythfrontend
