Watch Halo 3 Films without Correct Profile

Hi,

Recently I have been trying to record my friends halo 3 games on a capture card. I have his hard drive, with the games on it (I checked in system memory), however it seems you cannot watch unless you are logged into the profile that played the game.
He forgot his password, and in trying to recover it got more locked out of his old account.I was wondering, while we wait for his account to be recovered, if there is a fix for viewing videos on a profile they don’t belong to? Like maybe a local fix or just a hack or workaround?

Thanks!

Look on his file share.

No, I’m talking about all the videos from his hard drive. Not just the handful he’s hosted on file share.
