OK, I am using Roxio My DVD (a part of Creator 2009). The video was recorded from a live TV show using Windows Media Center and then turned into a .wmv file by Windows LIve Movie Maker. The file plays as widescreen and it was recorded from an HD tv program. When I play the wmv file in windows media player, it plays widescreen. There is no "video/advanced" choice on my edit menu, but I do select "Project settings" on the file menu and select 16x9. The menu shown is then widescreen and the video ON THE MENU looks widescreen, but when I preview the video or create it, the video becomes 4x3 size in the actual video. I have seen others with this problem and it had to do with not recognizing the correct file ratio. There really isn't anything more I can tell you. Perhaps My DVD just doesn't work properly with wmv files, (and I am sorry I got that last letter wrong, I meant wmv, not wmf.)
