How to catch "Sorry, This video cannot be played" error on VideoView

I have a VideoView and I am streaming videos from a remote server. Most of the times It would play the videos very smoothly. But sometimes, it displays an error message "Sorry, This video cannot be played". I have a hunch that this is more on the supported video formats. However, I don't know which are the supported formats. My question is "How can I catch this error (e.g. Prevent the error message from appearing)"? I am using Android 2.2 on this project. Any advice would be greatly appreciated. :)
