It depends on p7zip, available from Salix repositories, and libmediainfo and libzen; the latter may be installed using Sourcery. In fact I'm not absolutely sure about libmediainfo and libzen, so it would be interesting if you could try it without first, then install them too and report what difference you see.
Please do let us know how you've been getting on with it.
Another application that might be relevant is mediainfo, also available from Sourcery - if you install it libmediainfo will be installed too, and libzen in turn.
