The joys of vid tech

I've had to upgrade from Premiere 6.0 to Premiere Pro CS3, which is kind of like going into your somewhat grubby but pleasantly familiar bathroom and suddenly finding a giant array of high-tech knobs and spouts and mystery tubing where your old shower used to be.

Question for vidders: how the hell do I turn off the Frame Blend option for all clips in my project file/on my timeline? Anyone? Please?

I'm not even sure what Frame Blend does, but I strongly suspect it's blurring the clips unnecessarily. Right now the only option I can see is turning it off on every single clip by hand, which is not good for my RSI or my mental health. Help?
