Inside the Blu2 case, you have the CD transport + electronics to read the transport, plus the M Scaler electronics. Rob may be trying to say that selecting standby mode, puts the CD transport plus associated electronics into standby, but still leaves the M Scaler electronics active. Because the M Scaler electronics are still active, you are able to connect your macbook and still use the M Scaler to process the data and then feed your DAVE. Also remember that when people have suggested including the M Scaler inside the DAVE case, it is pointed out that the M Scaler requires power at 10A at 1V (ie 10W). When you use your Macbook to feed the M Scaler, it will be generating 10W of heat, which probably explains why your Blu2 case still feels warm, when you were expecting it to be cool.
