Just an update, i got a video card for $40 (geforce gt210) that has HDMI, plugged that in to the PC, and boom, no ghosting whatsoever, it's now crystal clear. The card also pics up the audio from the bus and sends it along with the HDMI video, which is nice - less wires. Thank you all for your help. It seems I should have stopped worrying about what might be causing the ghosting, and just upgrade to HDMI. I will probably do the same for the xbox, seeing how going HDMI on the pc has completely eliminated the ghosting.
