Simple Program To Rotate Video

All I’m looking for is a program to rotate any video, no matter the format, in vista. I’ve used Ulead Video Studio 11 and I don’t like how when the video is rotated you have the letterbox effect. I also tried Virtualdub and it work’s well but I have some .asf files that won’t work with it. I guess I could just convert it so it could work but I was trying to see if there were any solutions that could save me time in the future.

Virtual Dub v1.3c supports asf to a certain degree. It’s an older version so you’ll have to search for it, but it is easy to find.
