I don't know about your camera but with mine I get similar poor results and I put it down to the fact that the emphais is on images and visuals. I tend to think that an off camera mic is best- the built in ones seem, to me, to be a bit on the cheapo side. My opinion based on my uisage of digital cameras. In fact I am thinking of getting one of those digital cameras with decent audio-there is a Zoom one but a friedn has one and the video isn't that great but I beleive there is a new one coming out(it may already be out) that is well specified with both video and audio.
