My opinion is that it isn't likely to be the camera, except if something is terribly wrong with the camera or connection. Common problem with "domestic" footage is that it is usually too deep, especially when compared to professional production (3D movies). In pro movies (made for large screens), the parallax between the cameras is usually not much more than 1% of the picture width, while it's recommended that home movies should not exaggerate with parallax as well (max. about 3%).
Moreover, the freshmen in 3D are usually taking videos/movies too close to the nearest object (let's say, the nearest object on the picture/video is closer than about 2.5m on Fuji W3). If adding some zoom, it becomes even worse. Professional production is also trying to avoid highly contrasty objects, especially if they are in the background or much closer than stereo window.
Please, check your footage first if the parallax is low enough (let's say less than about 1/30 of the screen width).
