Is this the right battery for my Macbook Pro 3.1
May be not. Here is the Apple battery and an OWC replacement:

You may have a third party battery of mixed quality. The best sources for MBP batteruies are the ones I have provided links for.
90 minutes of video use may not be that unreasonable for the old MBP batteries. Video is resource intensive and if my memory is correct, other 'normal' use allowed for 3.5 hrs ± battery run time on the older MBPs
