Hello, As I await the arrival of my new TV in store, I've been thinking of calibration. I've got a few discs with THX Optimode (the latest being Romeo and Juliet: SE). Ideally I would like to avoid buying Avia or VE as they are pricey in Toronto. My question is: Will the THX Optimode video tests be sufficient to calibrate my new TV or will those other discs have tests that will really make for more improvements? Thanks, Andy PS. Does anyone know where I would be able to rent one in Toronto (ideally somewhere in Scarborough).
