           Summary: UVD decoding of MPEG2 streams doesn't work on CEDAR
          Severity: normal
    Classification: Unclassified

On my system with CEDAR graphics decoding mpeg2 streams with vdpau doesn't
work. Only a black window is showed and mplayer2 says:

On a SUMO based system this works correct.
