Had the camera less than a month and it suddenly stopped being recognized by any of my systems although they could access older sony fine. Camera is fine in all other aspects. I am generally careful in hooking up firewire devices (even in cases like this where no power should go to camera due to 6-to-4 pin connector). Fine print on Amazon affiliate says they do not provide service so I will have to contact Canon directly.BTW, J&K; Camera delayed sending camera and made unsolicited sales call. See >http://www.resellerratings.com/forum/showthread.php?t=119938 for various complaints against them.
