What do you do if another package was prepared for and tested with the
newer version of mplayer?

Example: repo A (priority), repo B

  "libfoo 1.0"    is from repo A
  "libfoo 1.1rc2" is from repo B

  "bar" from repo A  was built and tested with libfoo 1.0 from repo A
  "baz" from repo B  was built with libfoo 1.1rc2 from repo B

You install "bar + libfoo 1.0" from repo A, the higher libfoo 1.1rc2 is
ignored due to prioritized Apt-pinning.

What happens if you want to install "baz"?
