I had to get a plugin. At apple they give a choice for XP: quicktime with itunes. For QuickTime 6.5 for Win 98/ME quicktime only - well guess what. quicktime only works in xp. Used to be only Mac and QuickTime 6.5 for Win 98/ME can have quicktime only, I think. They offer no "only" options for xp - you just have to take it.
