This is one of the reasons why you do NOT buy JVC cameras. .Mod files are a BITCH to work with - generally, they require some sort of converter program, and generally that comes with the camera or you have to buy it online. Usually, though, I think you're stuck using the stupid program that comes with the camera.
Search YouTube and Vimeo for HV30 footage - some of it is absolutely fantastic - you just have to be smart with the camera and know what you're doing with the computer.
But yes, like Allen said, when buying cameras, stick to Sony, Canon, and Panasonic. The rest are soccer mom/pewpie brands.
