This happens with Windows media player and windows media player classic.  I can us vlc and I do not get the red vertical line running down the screen.  No matter what movie I play the line is there.  But it does not appear untile I actually push play.  When I originally open the player I have a blank black screen.  But once I push play the movie starts and the red line is there.  Fast forward, rewind and pause, the line remains.  How do I solve this problem?

    Did you install a codec pack or video software? That may be the cause.

    Did you install W7 as an upgrade to Vista?

    One other source of trouble (not likely) is an incompatible video card driver.

    Also Catalyst settings will be responsible for such a line.

    with AMD display open up either Catalyst or Radeon Settings go to Video tab then click "Demo On" it should say "Demo Off" after clicking the option.

    I had absolutely the same problem here and managed to find a solution for it. The option 'Tearing Test' was enabled for me. It seems like I pressed Ctrl+T combination and turned it on (wanted to create a new tab in a browser). You can also try to use this combination or go to View -> Renderer Setings -> Tearing Test and disable it.

    Wish you best of luck!

    For green line in VLC:

    Tools menu –> Preferences –> Video –> Choose OpenGL under Output options –> Restart VLC.

    Tools menu -> Preferences -> Video -> Uncheck "Accelerated Video Output (Overlay") -> Restart VLC.

    Just right click on RADEON settings on your system stray and under VIDEO PROFILE choose default.
