I’ve been struggling with something similar and JVC in the UK were no help at all. However, I learned that a problem can occur on the DVM600 – avery similar model. A guy called Dave Walton at JVC USA posted a fix in November.

The problem occurs when the input for the HDD/DVD is set to DV while the DV deck is selected. To rectify this make sure that the input selection for the HDD/DVD is something other than DV (use F1 or L1) while you are using the DV for capture/export with an NLE. In certain circumstances this can cause 2 drivers to load simultaneously and then proper communication is not established via IEEE 1394. His advice was to reset the SR-DVM70/600/700 units by holding ‘stop’ and operating it for 3 seconds. This apparently resets all the microprocessors and the IEE1394 id.

I did this and also then disconnected both units from the mains for a few minutes. When I powered back up everything worked a treat. I hope it works for you!
