What version of mplayer? I use:
$ apt-cache policy mplayer
  Installed: 2:1.0~rc3+svn20090426-1ubuntu16+medibuntu1
  Candidate: 2:1.0~rc3+svn20090426-1ubuntu16+medibuntu1
  Version table:
 *** 2:1.0~rc3+svn20090426-1ubuntu16+medibuntu1 0
        500 lucid/non-free Packages
        100 /var/lib/dpkg/status
     2:1.0~rc3+svn20090426-1ubuntu16 0
        500 lucid/multiverse Packages

For HW acceleration, try xvmc. Might be supported on your card?
XvMC is supported on Radeon-4000 cards (which have UVD) by Catalyst
driver from 8.10 and higher at an experimental level (meaning that it
doesn't work "out of the box".)[4] (See also X-Video Bitstream
Acceleration). Motion compensation support in other ATI/AMD hardware is
planned for the future. (Now all hardware has support for MPEG-2
acceleration on iDCT and mo comp levels).

Works for me with my Intel Movile 4 Series chipset.

BTW: I used to use the PPA versions of mplayer & smplayer (rvm's ppa)
but was having issue on my laptop (stutter, pauses, etc), so I went back
to the medibuntu version instead.
