I've hit this (sort of) problem before. What you need to know is that a resolution of 720x576 is in fact widescreen. It's also 4:3 at the same time. Confused? You will be. there is not difference in dimensions between standard and widescreen. All that changes is the 'shape' of each pixel. The trick is to tell the wmv file that the pixels should be displayed in a different shape to get the aspect ratio you want. I never found a way either when I looked for it. Maybe someone can offer help nowadays but what I did is....

Simply stretch the image out to 1024x576 which (for square pixels) is what widescreen actually look s for. WME can do this for you.
