As a further aside to this, I thought the issue may have been that the videos had been recorded on the camera, put onto a computer, burnt from that computer onto cd then taken from that cd onto my computer. To rule this out, I took the video straight from the dvd out of the camera and put it straight onto my new pc - alas, this too did not work
Getting desperate here, video editing is the whole reason I spent a large wadge of cash on this new pc
