Can I easily/how can I tell if the 1394 board in my dvx100b is indeed Fried, I suspect it is. I have successfully used this port for many a download from this camera in the past but I recently lent it to a buddy who downloaded to his mac (I use a pc) and now that the camera has returned to me the computer will not recognise that I have even plugged anything in ( I suspect he did not heed my warning of plugging in with the camera on ) unless interfacing with a mac has somehow reconfigured it???????
