I just played it on a 2008 3.06GHz iMac, a 2009 2.53GHz MacBook Pro, current i7 iMac, an iPhone, and an iPad. I watched the 1080p version on the iMacs, 720p on the laptop, and whatever the iPad and iPhone show by default. It plays pretty smoothly on the iMacs and laptop, with occasional jerks you see on flash videos. I then compared the html 5 presentation of the videos; these played the same as the flash versions. It played the same on the iPad and iPhone.
So you saw some jerkiness on both your imac and mbp, huh? Could you tell any difference on the side by side video in the ClipWrap folder?
