WIll fire up my dv cam a bit later and get / make some sort of a guide for you.
Mine has to be in DV mode with a option = tv=on for a extenal out or something to have the out port to tv active otherwise it does not send signal via this or in the right mode.
Firewire "1394" is the way to go for video but depending on the camera the usb is only for still / memory card part of it , differs from device to device.
Firewire looks like a rechtangle with one side rounded = 6 pin or the 4 pin = small square or a funky figure 8 with 1 side straight.
Usb = rechtangle and flat almost or small = rechtangle with slanted sides so top part is wider than bottom if I remember correctly.
kino / Cinelerra both work if camera is in playback mode and not recording mode depending if yours have this but might work either way.
Some of them act as a vhs type device in playback mode ie: still camera / sd card reader device / camera / video camera / vhs / tape drive device and all glued together + interacting during recording mode or something like this and spilt appart during playback and acting as seperate but glued together parts for say video transfer.
Maybe you can get a online manual for it if possible as this would help to get the correct settings for video transfer.
Might first want to get it working in windows if you have a copy and then use it in Linux just to make sure everything works as this should limit bug's / things that can go wrong.http://www.camcorderinfo.com/bbs/t136884.html
Will post how I get mine to work in a bit / next 48 hours about.
