I tried that too... I tried two third party video players to play the videos I took but nope... the camcorder is brokenUsing Bytecode's latest kernel, I was able to take video, just couldn't play it then.
When I stop recording the camera app freezes, I had to use the home button to get out of the camera app, then use the recents apps. Then I could go back into the camera app and it worked fine again.
