What version of mplayer? I use:
$ apt-cache policy mplayer
*** 2:1.0~rc3+svn20090426-1ubuntu16+medibuntu1 0
500 http://packages.medibuntu.org/ lucid/non-free Packages
500 http://us.archive.ubuntu.com/ubuntu/ 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".) (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.
