I've downloaded the mp4 versions of the new VI tutorial videos. The one titled 02_VI_New_Overview_800x450 plays until 04:57 and then the sound stops and the frame freezes, though the movie seems to be still playing.
I'm watching it using Quicktime Player 10.1 on OS 10.7.4
I also tried with VLC and the movie just closes at that same point.
Is it just on my system, or is there a fault?
