hi unfortunately most of my quicktimes are plastered with 3ivx expired graphic and this is the first time it happens. since i've been using os-x (tiger 10.4) and that is a few years now quicktime never got this message (obviously it was playing 3ivx codecs all the time too). and i've got perian installed. how come this now happened? does it have to do with 10.5.3, anyone else experienced that problem?
