Has anyone used Magic Bullet looks in Vegas to work on AVCHD files?

I'm worried that the AVCHD is so CPU intensive that it will make using MBL unbearable.

Thanks!

I am using it, its alot faster than mb hd which came with v7, that one practically stopped my computer. with looks, i put in new video card, yah it runs real hot, my machine is a dual core, only runs at maybe 60%, THE AVC is no more of an issue than mpeg4, right now I am putting a 5 min clip, corrected with looks back to m2t, it will take a while
