Change Aspect Ratio 4:3 Video to 16:9 for Widescreen Display

Hi all, I'm a newbie and tried to convert a 4:3 source video by setting the (display) aspect ratio to 16:9. The resultant video when played back does present itself as widescreen but unfortunately the actual image is incorrectly stretched. How would one go about converting the source video from 4:3 to 16:9 correctly? What programs would I need to do this without compromising the source video quality? Any feedback most welcomed, many thanks in advance.

It's well-known to all that the aspect ratio of a video means the ratio between the width and height of the image and the most common ratio are 4:3 and 16:9.
