A first look over at CNET at the GR-HD1 from JVC, the world’s first and only high-defintion camcorder for consumers. Only worthwhile if you also happen to own a high-defintion television as well, and that while it’s resolution is great, since the GR-HD1 uses a one-chip imaging sensor it isn’t as good at capturing color as well as a standard-definition camera with a three-chip imaging sensor.
