lag

I am setting up a media center running Xubuntu 11.10 as a media center. It is using the XFCE desktop enviroment. I have the NVIDIA drivers installed from the Additional Drivers program, and uninstalled all but the esennitial software. The computer is a Dell Dimension 3000. You can view detailed technical specifications here. The graphics card installed is a Geforce 8400 GS. I have installed all updates through Update Manager. What can I do to fix the horrible lag? It makes watching TV impossible.I have uploaded two videos of the lag, here and here. The second one does not have sound because the sound stops playing on some channels that lag a lot. The TV card is a Hauppage 950q USB, and the TV recording program is Kaffiene. Please help me with this, I am trying to do this to show how great Ubuntu is to the rest of the family.
