red lines acrossed under the real media

[kidalive]

After updated the kalyway 10.5.4 to 10.5.5 failed I installed IATKOS 4I AND Updated to 10.5.5.All seems works fine to me.BUT when I installed realplayer11 I found when playing real media format files in a fullscreen mode a red lines angle would appear under the screen. == It never happens when I was using the Kalyway MAC OS X.So I wanna know why.ANYBODY come across the same issue like me?What`s going on with this edition?
