I finally got around to playing with the Sony HD camcorder two years ago. I know a bit late, but a lot has taken place. It records 1080i. To view it I have to use a sony program, I think. I am considering giving the camera away and getting a Panasonic TM900 that records 1080/60p. Do you need a proprietory progam to play back. Is this standard with all HD camcorders?
