How to catch exceptions

[Brent Taft]

I am trying InTheHand Media player - and so far it works great. However, I did notice that if i try to play a video file that is corrupted - it will crash my app. I have the media element in XAML and using data binding to play the video. Is there a way to prevent to catch these exceptions so the whole app doesn't go crash?

This is possibly in the code used to load the metadata, are there any clues in the stacktrace?
