I have both 256mb and 512mb 8400gs cards and they are both great. Never knew there was a 125mb version so can't comment if that's the problem. You need a DXVA capable decoder. When DXVA is working CPU usage will be below 10% (around 5% on my wimpy hwe). For mpeg (broadcast) get Cyberlink pdvd7/8/9 (clvsd.ax). For h264 get mpc-hc decoder (mpcvideodec.ax).
