The GZ-MG27 is a 20 GB camcorder. The big innovation is that it can be teamed up with a DVD burner for direct footage transfer even if the owner doesn’t have a PC. JVC has also upped the transfer speed too. The GZ-MG21 has a 680k CCD, and offers a powerful 32x optical zoom. It also features 4.5-25 hours of video storage.
