playing videoview in tab controls not working and cause force close

Question

Everything works fine, but in the third tab I have a videoview. It plays the video until I click on the screen to use the mediacontroller and then the app states, "Unfortunatetly 'APP NAME' has stopped" I have searched for nearly two weeks, but don't understand why the video plays, but stops the app(forces closes) when trying to use the mediacontroller..? I have tried this on a different mobile and it works and have tried setting up the tabs indiviually, but I get the same result. I have highlighted the third tab below using //PROBLEM USING MEDIACONTROLLER. I can post you the XML if you like, but this appears ok as the video does play... Please, please help.
