Question about sony DRV TRV9E DV input/output



I have a question about the dv output on my Sony DRV TRV9E camcorder.
I have heard it is possible to reprogram a little chip inside the device so that the output can also be used as in input.
American devices have this option as a standard but because of the import taxes this option is not availeble in europe.
Unless you buy a expensive remote control (about $200) wich will reprogram the chip, but you will only use this once.

Does anybody have any experiences corncerning my problem?
Does anyone have such a remote control?
Are there any other (cheaper) ways?

Any help is welcome
