Hey all! I have been using my Ibook G4 for a while to watch dvds on but all of a sudden about 4 hours ago these green and orange lines have appeared and are cutting up the image... The strange thing is is that when i use another third party dvd player on my ibook these lines still appear but do not on VLC (I would use VLC but it flickers from time to time). Also i have an old desktop G3 and these lines dont appear on its DVD plaer... any help???
