Are you using a nvidia 8x00 card ? I remember that the original BR2 wasn't working properly on these cards till nvidia released driver version 100.x or so.
The pre-rendered videos have been always an issue for a lot of people, even without my patch (personally, i never had problems with them, in any of my old rigs: 9800Pro, 6800U, 7900GTX & 8800GTX).
The patch has been developed on a 8800GTX with several Forceware versions, starting from version 15x. through actual version 169.x.
I'm glad to know that the patch works for you after the driver upgrade.
Enjoy it !
