It would have helped if you gave the options you were using, but
here goes anyway:

mplayer -vf expand=640:480 <path-to-video>

I've tested it with a file, but not with any streaming video.
If the source video prescaled and you want to scale it to 640
pixels, then use:

mplayer -vf scale=640:-2,expand=640:480 <path-to-video>

Cheers,
Rob
