I am trying to use this script to archive my shows as .mkv's but it requires mkvtoolnix, and when I try to install it I get

root@mythtv:/etc/apt# apt-get install mkvtoolnix-mb

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
mkvtoolnix-mb: Depends: libc6 (>= 2.3.6-6) but 2.3.5-6 is to be installed
Depends: libflac7 but it is not installable
Depends: libgcc1 (>= 1:4.1.0) but 1:3.4.3-13 is to be installed
Depends: libogg0 (>= 1.1.3) but 1.1.2-1 is to be installed
Depends: libstdc++6 (>= 4.1.0) but 3.4.3-13 is to be installed
Depends: libvorbis0a (>= 1.1.2) but 1.1.0-1 is to be installed
Depends: libwxgtk2.6-0 (>= 2.6.1.2) but it is not installable
E: Broken packages


any suggestions on how I can install this package?

thanks
