I have an HTPC running Windows 7 Media Center. This is rather hard to explain, but when watching something in widescreen, there will be two lines going down the screen where the black bar of a non-widescreen presentation would end. I have attached a shot of it.
Can anyone shed any light on why this is happening and what to do to fix it? It is directly related to Win 7 Media Center as the lines do not appear when the program isn't running. It does do the same thing when not playing anything within Media Center, just browsing the menus.
