How much footage can Black Ops' theatre mode store?
Solution 1:
According to Gamespot, the clips save to callofduty.com:
You can only save six clips. These are the six you can keep in your fileshare. You cannot download any to your HDD. You can't get the clips rendered to your computer, you can save screenshots to your computer from callofduty.com/blackops. Go to the theater tab on the site and you can select and save your screenshots.
