问题
I've got the image picker working in a popover on the ipad, but when running in the simulator when I select a video in the picker it says its compressing and then gets stuck.
Nothing happens, the delegate function never gets called.

I found one solution - it works on the physical device. I dont know why it crashes on the simulator, but if I run the app on my Ipad it works fine.

It's a late answer but you can fix it by following this procedure: go to the simulator hardware menu and select TV out: 640x480 after that try to run your app from xcode and then again go to the simulator hardware menu and select TV out: Disabled.
