How can I rotate a small digital video 90 degrees counterclockwise?

A small video was recorded with a digital camera, but the camera was held in the "portrait" position. When played on the computer it is sideways. Is there software that will allow me to rotate the video and resave it so it always plays in its new upright position?
I hope you can help! Thanks so much...

According to this Adobe Photoshop site, repositioning of photos is just one of the multitude of things you can do.

Yes, there is a free program that you can use called Virtualdub (http://www.virtualdub.org).

open the avi file
set audio processing to "direct stream copy"
set video processing to "full processing mode"
click on filters and select the rotate filter, configure it as necessary
back in the video menu click compression and choose a codec (divx is good, go to divx-digest.com/software to get one if you dont have one already.)

save the avi
