In HDV mode 'PAL' is no big deal and you don't even need a PAL camera--just shoot in 25/50p and use the appropriate timeline in your NLE.* In DV mode you'll need a PAL model, and all of the same implications apply as would with any miniDV camera. I would advise against mixing 25/50p material with 30/60p material, however, as the framerate conversion can sometimes produces weird effects.
*One caveat: shooting 25 or 50 fps (in any formant including film) in a country such as the US were the mains power (AC) is 60 cycle can result in lights appearing to flicker--you'll have to adjust the shutter speed to eliminate this; in general, reducing the shutter speed should solve the problem. Of course, you'll be able to see this in the viewfinder.
