If you want to reverse the video, you can use the Invert filter from VirtualDub. From the video menu, you have access to the filters. From the audio menu, you can choose whether or not to process audio. You can download VirtualDub and find tons of tutorials on Google as well as their site on how to use it.

... sadly enough, that wasn't one of the two possible meanings of reverse i was thinking of. I was thinking left/right inversion or running the video backwards... – Journeyman Geek Jan 4 '12 at 12:29
I agree, Journeyman Geek. I feel what this fellow wants to do should be called "Inverse Video". – kingchris Jan 4 '12 at 12:47
@JourneymanGeek: The left/right inversion is called flipping, where the last one is usually called backwards playing the video. Back in the days this is what reversing a video is and it probably still is now. But indeed, the OP could specify what he is after because it is a confusing term. – Tom Wijsman Jan 4 '12 at 15:46
