Since no one else has chimed in, while I can't say specifically, I do have a thought.
Movie conversion software often depends on other programs. For example, maybe you have VLC or a different version of QuickTime installed than your friend. Visual Hub might depend on some codec or component found somewhere else that your friend does not have. I know this is the case with Handbrake (video conversion software), that required something from VLC. When VLC changed, it temporarily broke Handbrake.
Like I said, just a thought.
On a Mac since 1984.
