Audio Sounds Like It's Skipping in Lightworks
Get a better computer. The fact that the audio sounds fine in other apps means it was recorded fine, and the file represents the audio correctly. When you open it in your editor though, that's a much more complex operation than simply playing the video in an optimized player. So, I think this is a performance issue. I've had this problem myself with cheaper computers, and back when I switched to HD, I had to buy a new machine.
