The short answer is yes you can use a camcorder bought in the US in Spain, however, play back on a TV in Spain will be a problem. There is a quite a difference between NTSC and PAL. Screen resolution..NTSC is 720x480 (4:3) vs PAL at 720x576 and frame rate of 30fps(Frames Per Second) for NTSC and 25fps for PAL. There is a conversion solution for you. You can get a USB capture system for your computer and convert your NTSC to PAL to play back on your TV. Go to
