I went to watch the High Definition _Fantastic 4_ trailer at [Apple’s Quicktime Trailers site](http://www.apple.com/trailers/), but I couldn’t quite watch it in real time. I have a 1 GHz iBook with a 32 MB Radeon something or other video card and 1.25 Gigs of RAM. What kind of specs will I need to play the 720p video? What about the 1020p? ---

Jest making sure, but you do have QuickTime 7.0 installed? ---

I assume it was installed with Tiger. The video wouldn’t even run without Quicktime 7.0, would it? As it is, it plays, but very jerkily. ---
