Package: mplayer Version: 2:1.0~rc3+svn20100603-0.0 This is a package from debian-multimedia, not main debian archive. You can either install libvpx0 from unstable (as I done) or downgrade mplayer to version 2:1.0~rc3+svn20100502-3 (from squeeze [main]) which is not linked with libvpx at all. --- Rinat
