The video is in H264 High profile, you can read this in any Directshow based application with FFDshow filters, or in VLC (multiplatform, no codec needed), or in any application supporting H264 high profile (nero, power dvd w/AVC etc...) Quick Time barely supports H264 main profile and is not optimized at all, only use it for pure Quicktime stuff.
Viewed with VLC and vuze embedded player on Vista.
