The real question
The real question is why would any one use quicktime as their media player anyway. There are plenty of quicktime alternatives that are DRM free and much more responsive.
I cringe at quicktime and its taskbar icons and its sluggish response as well as generally crap interface compared to other decoders as well as its size and just generally the fact that it has mostly sucked since its inception.
It feels like apples version of bloatware.. it doesn't do much but its slow and cumbersome and now riddled with DRM.
