You can do this if your computer has a TV Tuner card.

Hi, I recommand you to try google picasa.

picasa is a Google's photo software. It's what should've come with your camera.

It can Edit , organise and Share you picture and small video flips.

It's very easy to use and is free, just like Google

Download it free in here:
