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.

    CTRL + T causes it.  Use this shortcut key to toggle it off.
