Here is a small, portable USB video and audio capture device with some decent specifications. At 720 x 480 resolution you get DVD resolution from the EasyCAP although I would think you only obtain that using S-Video rather than Composite.

ShenZhen also ships the Ulead video editing software which is user friend and ideal for someone who’s looking to take a first stab and create home videos.
NTSC format gets you 30 fps while PAL gets you 25fps, and get this; you only need 256MB of RAM to pull this off – although I would highly recommend at least 1GB of RAM when doing ANY type of video editing.
