I have a double-sided Gattaca R3, should I upgrade to the Superbit R2? I've also got the standard R2 Crouching Tiger. There's one thing that I noticed, in the first sword fight scene with Jade Fox, and one or two other kung fu scenes I notice "blurring" due to the sheer speed of the fighting. When I saw it in the cinema I'm sure there wasn't any "blur". Could it be possible the Superbit version might eliminate this effect? Or could it be my DVD player producing such a effect?
