I don't have problems with codec performance in ubuntu 10.04. I would
try playing the videos with mplayer, totem and/or vlc to see if the
performance problem is a codec one. Also do you have a graphics driver
with 3D hardware acceleration? if you type
glxinfo | grep direct
is direct rending a Yes or a no?
(if you don't have glxinfo installed, it's in mesa-utils i.e. sudo
apt-get install mesa-utils)
