I need to know the name of a software to turn or rotate video?

My digital camera gets used by my wife and she likes to take videos sideways but windows media player, real player etc do not turn the video automatically, any ideas welcome.

Learning video editing can be fun. You can add personal touch to your videos. Try the link, you can use the software to rotate your video files and save them to other files. Or browse for free video editor on any search engine. Good Luck!

Easier to teach her not to do stupid s*** like that.
