Hi, please can someone help me I am totally lost about by camcorder.

I have a Sony TRV16E, I have once before viewed the tapes on a PC through the USB connection.

I have tried to do thi so n my own PC and when I plug it in it sees new Hardware but cannot see that it is the camcorder, I have tried re-intalling the drivers and have also been on the Sony website to get the latest. I cannot seem to be able to view as I did before.

Because I want to edit it and make DVD's I went out an got a firewire, I have installed this OK and it can be seen in the device manager. When I plug the camcorder into this it cannot be seen at all, does not tell me there i snew hardware or anything. This uses the same plug on the camcorder as the USB cable.

Any help would be great
