Halo Reach's BROKEN Theater mode.

I have this book trailer project I have to do for English class. So, I decided to choose a Halo book and make a book trailer in Halo Reach. Because that’d be cool.
My friends and I went into custom games and acted out the scenes for the trailer.
When it was finally over. I went into theater mode to film it like a Machinima, but something terrible happened.

Film Error
An error occurred while the film was playing.

I don’t understand. What error?
I have went into it again to see if it was a one time issue, turns out, it’s not. It’s like this for all of my other films.
So, I started to experiment, going on 360, going offline, restarting my Halo Reach, restarting my Xbox, and even trying to time the pause button when the error would happen.
None of this worked.

I have a problem, and I would like a solution.
If anyone has a solution for this frustrating problem, please share. It would be greatly appreciated.
I’m tempted to uninstalling my Halo Reach then reinstalling to see if that works.
That’s the level of frustration I’m at right now.

I think reach is having some issues with reviewing game footage. This has been an on going issue. See this post has the same issues.I don’t believe there is a solution as 343 need a to fix it on their end.

To test this error, I’ve decided to uninstall my Halo Reach to reinstall the game afterword.
I was thinking that I could refresh my Xbox’s emulator and see if it works.
It doesn’t.
I don’t recommend uninstalling it, because the same error still appears.
343 really need to fix this, multiple people still play Halo Reach.

I think it broke when they updated it for the Xbox one.
