Headhunter cd2 patch?

[Excalibur007]

Hi,
I have seen the Headhunter CD2 patch for download, but I have not seen what it is actually for.
What does this patch correct?
I have beaten Headjunter once before, but my game save got corrupted after finishing the game. Is this what it's for? I am now playing through it again and am on CD2. I have not saved on CD2 yet, and I don't want to save until I know what the patch is for, (just in case it corrupts my save again).

Thanks for any help with this.

P.S.
Also, toward the end of Disc2, there were a couple of videos that were replays of earlier videos. The text was correct, but the video was not. ex: It replayed the video of the escape from the prison with greywolf instead of the correct video. Is there a fix for this?
