just shot a wedding today as well. Unfortunately, I don't have 32gb cards to shoot continuous for the ceremony,so GOP1 was not an option at least for this. Also unfortunately, I could not get any of the settings files to download/open yesterday when I was trying to get some cbrandin stuff. All I had downloaded previously was high nitrate low GOP stuff, which all eats card space too much. So without the cbrandin settings, I reverted back to original firmware. That's okay, though, the other camera I used was a Canon HV20, so quality is not paramount. It'll all look fine once its on DVD anyhow.
