So you’ve installed Windows Media Player 10, and now some of your video plays upside down, or doesn’t play at all. You’ve realized you had it better with Windows Media Player 9, but you’ve tried everything to uninstall it, or reinstall 9, but you just can’t get it to work. Yep, I was once like you. Until I found this site with instructions on how to rollback to WMP 9.
I’ve also copied the text here just in case it disappears from the original site somehow.
