I tried it here on this system, The app does not stop responding.
I do get errors when it tries to play the video. The error pops up on IE and says that it can't move focus to the control because it is invisible, not enabled or is of a type that can not receive focus.
The test system is XP sp3. Not sure which IE version is on here either 7 or 8. I don;t use IE and have not allowed the newest version to be installed.

If I clear the error and click on the link again or another link the program works but I get IE errors on the links.
