    My main question is this:

    Is the dv 4pin firewire connection on my camcorder only firewire 400? The new connection on my new iMac is fw800 for sure, but when connecting the two, it will automatically revert back to the fw400 mode right?

    Is there any way to get a fw 800 performance out of a 4pin connection from my camcorder.....or am i stuck with fw400 performance?

    Thanks for the help. I was worried about that. Is there any camcorders out there that are set up for fw800 currently?....or is everyone waiting for USB 3.0

    I don't know of any that are FW800, the ports are not all that common.

    you can still get quality video through fw 400 though correct? I have noticed it is significantly better than usb 2.0......thoughts?

    FW400 provides more than enough bandwidth to get the data off the camera in real time. There's no need for FW800.

    Yes. USB video is terrible. DV only uses a small percentage of the firewire 400 bandwidth, so having it go over 800 would not be any different.

    Lethal's correct... no need for FW800 and manufacturer's aren't "waiting for USB3"

    to illustrate:

    DV is 25Mbps
    DVCProHD is 100Mbps
    1394a (4pin or 6pin Firewire) is 400Mbps

    Tape captures in real-time anyway, a faster port would be pointless.

    You won't even get close to FW400 speeds from a camcorder. Camcorders equipped with Firewire are FW100 devices - meaning that the absolute fastest transfer speed from a camcorder will never exceed 100mbps. No where close to FW400 or FW800.

    But as has already been stated, the data rate of the video format wouldn't be able to take advantage of a faster transfer anyway.
