I have a Canon HV30 that needed FireWire to get the video off, otherwise I was stuck with composite and finding some random gadget that could rip video. The C875 is the best and smoothest soultion I have found yet. I basically popped the device out of the box, plugged it into a portable USB battery, plugged the HDMI cable from my camera to the c875 input, popped a memory card, pressed play on the camera and started the recorder. The file came out as a . Ts file, but if you go to the support site there is a program that converts .TS files to .Mpg4 and it works. Mind you I haven't used this product more than a day. So far I'm impressed. It kept me from throwing out the camera and there seems to be a ton of options. So far my only complaints are that I called support and left a message asking about if my camera would be supported and got no response. The other issue that may be camera related is the video is not sharp on my 55" TV.... Don't get me wrong I can live with it, just noticeable.
I would recommend this to a friend
