Flicker when Filming in NTSC Under 50Hz Lighting

I recently shot about 60 minutes worth of footage on my (American- NTSC) miniDV digital camcorder. Footage looks great-- except that everything shot under fluorescent lighting flickers! The reason is that all fluorescents flicker at the frequency they're beign driven by. In America, it's 60Hz, which, given a standard shutter speed of 1/125, meshes quite nicely. Here, it's 50Hz, which clashes really badly. The solution? Use a 1/100 shutter speed. The only problem is that requires going to manual mode-- I have to see if there's a way to permanently set it on my PV-DV402 camera.
