how can i cut a video resolution

[nacho_cheese]

im trying to convert a video without it being squeezed into the actuall resolution
like for example im converting a 4:3 video to widescreen 16:9 and the video kinda get streched and squeezed
what im wondering is how i can convert the video in its original display without it being streched
what i think is that ill actually have to sacrifice some of the footage for it to fit the screen but that doesent concern me =)
if anybody has a software or something that can help me it would be greatly apriciated

4:3 looks like this on a 16:9 display. Otherwise it gets horizontally stretched or vertically cropped or both.

i think cropping is what im looking for but i need to make it 320x480 so it can fit into the ipod
are there any software that can do this?

Open it in Virtualdub and use the cropping and resize as necessary.
