kramer fire wire protector PT-1FW
 

Having had a fried fire wire port (no, I didn't hot swap or switch ) I determined to add another line of protection and bought a Kramer PT-1FW fire wire port protector. Whilst it works well with DV it seems that it doesn't work with HDV. Has anyone else had any experience with this device and could they please comment.
