Why can I not the entire game I played on Black Ops in Theatre mode?

It only shows the first 3:16's and then stops. Right before my freaking crossbow cross-map stick!

Did I do something wrong? This was the first time I entered theatre mode and pressed a few buttons I wasnt quite sure what they did. Is there any way for me to see the rest of my footage?? :-/

If there was host migration, theatre mode stops recording after it.
